Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513696, here are decompositions:

3 + 31513693 = 31513696
29 + 31513667 = 31513696
83 + 31513613 = 31513696
89 + 31513607 = 31513696
293 + 31513403 = 31513696
503 + 31513193 = 31513696
509 + 31513187 = 31513696
647 + 31513049 = 31513696

Showing the first eight; more decompositions exist.
