The only numbers that fall in this category are the numbers 31, 7, and 2. Thus, the biggest difference is between 31 and 7, which is 24. ☺☺☺☺

-----------
Most prime numbers are odd.
The sum of 3 odd numbers is an odd number.
--> One of the primes is the only even prime number, 2.

The sum of the other 2 is 38.
--> 7 & 31 by thinking about it for 31 milliseconds.
