All prime numbers are odd numbers, except for the number 2. The difference between two odd numbers must be a multiple of 2. So, if the difference between two prime numbers is another prime number, that difference must be 2.Examples:{3, 5}{5, 7}{11, 13}{29, 31}

Not necessarily. 71 is a prime number, 7 is a prime number, and 71-7= 64, which is NOT a prime number. In most cases, the difference of two prime numbers will not be a prime number. All prime numbers greater than 2 will be odd numbers. The difference between two odd numbers will be an even number. Unless that even number is 2, it is not a prime number. Here are some additional examples: 19, 13: difference 6, not prime 23, 7: difference 16, not prime 53, 31: difference 22, not prime 61, 59: difference 2, prime 113, 109: difference 4, not prime 293, 283: difference 10, not prime 331, 101: difference 230, not prime
