A twin prime is a prime numberthat differs from another prime number by two. The first few twin primes are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), and (71, 73).

A twin prime pair are two primes separated by 2. For example, 3 and 5 are twin primes. It is conjectured that there are an infinite number of twin primes.
The twin prime of 191 is 193.
