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.
Twin primes are pairs of prime numbers that differ from each other by two. Examples of all twin primes less than 100 are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), and (71, 73).
