Fermat's Last Theorem, first conjectured around 1637, was not proven until 1994 by mathematician Andrew Wiles.
Notes on verification
Well-documented mathematical history confirmed by Wikipedia, AMS, and academic sources; the 357-year gap between conjecture and proof is accurate. [tier=silver indep_score=0.925 clusters=2 claim_tier=notable]
