twin prime conjecture 

Twin primes are prime numbers which differ by exactly 2. The twin prime conjecture states that there are infinitely many twin primes—that is, there are infinitely many pairs of prime numbers (p, q), where p < q, such that q − p = 2.

The first few twin primes are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), ...

The twin prime conjecture is an important open question in number theory.
