Twin primes are pairs of prime numbers that differ from each other by two. 29 and 31 are twin primes.

Twin primes are two numbers with have a difference of 2 and that are both prime so 101 twin number is 103

Twin primes are prime numbers with a difference of 2. 11 and 13 are twin prime numbers (13-11 = 2), 31 and 37 are not.

Prime numbers that differ from each other by exactly 2 are twin primes. Examples of twin primes are 3 and 5, 17 and 19, 599 and 601.

For a 2-digit prime number (which are all odd) to be the sum of two prime numbers, one of the prime numbers will have to be 2. That means the difference between the sum and the other addend will have to be 2. Prime numbers that differ by 2 are called twin primes. There are six pairs of 2-digit twin primes. Your numbers are 13, 19, 31, 43, 61 and 73.

Because the definition of twin primes is: two prime numbers with a difference of 2. 3 and 5 are both prime numbers, and their difference is 5 - 3 = 2 → they are twin primes.

Twin prime numbers are pairs of prime numbers that differ from each other by two. The first few twin prime numbers are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), (71, 73), (101, 103), (107, 109), (137, 139)...

A twin prime is a prime number that differs from another prime number by two.ex. (5, 7)The numbers two away from 23 are 21 and 25 which are both composite numbers.So in short, no 23 is not a twin prime.
