Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517732, here are decompositions:

3 + 31517729 = 31517732
31 + 31517701 = 31517732
79 + 31517653 = 31517732
199 + 31517533 = 31517732
241 + 31517491 = 31517732
739 + 31516993 = 31517732
751 + 31516981 = 31517732
853 + 31516879 = 31517732

Showing the first eight; more decompositions exist.
