Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530696, here are decompositions:

13 + 31530683 = 31530696
17 + 31530679 = 31530696
37 + 31530659 = 31530696
47 + 31530649 = 31530696
53 + 31530643 = 31530696
59 + 31530637 = 31530696
79 + 31530617 = 31530696
89 + 31530607 = 31530696

Showing the first eight; more decompositions exist.
