ShowingImportancePrizesTopicTwin prime conjecture
The open problem that there are infinitely many prime pairs of the form (p, p+2). Claims about its truth, proof attempts, conditional or partial results (e.g. Chen's theorem, Zhang–Maynard–Polymath bounded gaps), equivalent reformulations, and computational verifications belong here; other prime-distribution questions stay under Number theory.
There are infinitely many pairs of primes that differ by exactly 2.

The number of twin prime pairs below x is asymptotically 2 C₂ x/(log x)².
