Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509796, here are decompositions:

5 + 31509791 = 31509796
23 + 31509773 = 31509796
47 + 31509749 = 31509796
113 + 31509683 = 31509796
137 + 31509659 = 31509796
167 + 31509629 = 31509796
179 + 31509617 = 31509796
239 + 31509557 = 31509796

Showing the first eight; more decompositions exist.
