Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507696, here are decompositions:

29 + 31507667 = 31507696
89 + 31507607 = 31507696
113 + 31507583 = 31507696
173 + 31507523 = 31507696
293 + 31507403 = 31507696
557 + 31507139 = 31507696
587 + 31507109 = 31507696
659 + 31507037 = 31507696

Showing the first eight; more decompositions exist.
