Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613636, here are decompositions:

7 + 31613629 = 31613636
13 + 31613623 = 31613636
97 + 31613539 = 31613636
199 + 31613437 = 31613636
409 + 31613227 = 31613636
499 + 31613137 = 31613636
877 + 31612759 = 31613636
883 + 31612753 = 31613636

Showing the first eight; more decompositions exist.
