Not evaluated
Ostmann's inverse Goldbach conjecture (family 013)
The gist
On October 6, 2026, OpenAI announced, for Ostmann's conjecture, a manuscript on the additive indecomposability of the primes, from an unreleased internal model.
DiscoverIA status on October 12, 2026: not evaluated, meaning no third-party evaluation found.
AI draft, not reviewedWhat has not been reviewed?

What it changes
A set of integers is additively decomposable if it is obtained by adding an element of one set to an element of another, each having at least two elements. If the manuscript were correct, it would establish that the primes are indecomposable in this sense, in the precise form it states.
What remains unclear
The Lean (a language in which a computer checks every step of a proof) is supplied by OpenAI: the repository marks its review “unchecked”, and no third-party verification has been found. The sources read do not say where the question stood before the announcement.

The result is declared neither right nor wrong.
To move to “Under review”: a public review under way. To “Peer reviewed”: a journal publication or a review by named experts.

Method
The manuscript “The additive indecomposability of the primes” is dated September 24, 2026; family 013 has only this one. The repository provides lean/docs/013.md and two Comparator statements (OstmannComplete.lean and OstmannPrimes.lean, in lean/ComparatorChallenges), but the family is absent from the sources of formalization.yaml, and history.md reports no revision of the manuscript. DiscoverIA status: not evaluated, meaning that no third-party evaluation has been found in the sources read. Set on October 12, 2026 from github.com (page read, quotation checked word for word: “describes the scope of the Lean formalization”).
Limits
No named third party: the recorded checks come from the claimant or from a platform tool. The claimant supplies a Lean proof; as of this date, DiscoverIA has found no independent verification of this proof or of the result.
