The Goldbach Conjecture is "Every even number >3 is the sum of two primes." The Conjecture will be settled, and the result accepted by the mathematics community, before 12/31/2020. "Settled" means either proven, refuted, or proven undecidable. The proof must have been available for public inspection for one year. Corrections for any major errors or omissions must have been publicly available for six months. (Inspection periods are included in the time limit.) The judge may shorten the inspection period for an independently checked numeric counterexample, or for a proof that is mechanically checked by a program of good reputation. The judge may either personally evaluate the proof, or rely on an expert or experts of his choice, or rely on the consensus opinion of the mathematics community.
