2 and 5 are the only prime numbers which differ by 3.

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.
My guess is you're talking about prime numbers with a prime gap of two.
Numbers with only two factors, the number itself and one, are called prime numbers. Examples of prime numbers are 2 (which is the only even prime number) and 17.
Two prime numbers which differ by 2 are called "twin primes".

The numbers are relatively prime or co-prime.
