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

Prime numbers have two factors. Composite numbers have more than two.
What is The difference between 2 prime numbers is another prime numbers what is it?
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}
Which prime number can be written as both the sum of two prime numbers and the difference of two prime numbers?
5 = 2+3 = 7-2
What two prime numbers equals 125?
The difference when subtracting the prime number 2 from the prime number 127 is 125. No other two prime numbers added together or subtracted from each other have a sum or difference of 125. All primes except the number 2 are odd numbers, and two odd numbers added together or subtracted will always produce an even sum or difference.
