Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507596, here are decompositions:

5 + 31507591 = 31507596
13 + 31507583 = 31507596
19 + 31507577 = 31507596
23 + 31507573 = 31507596
73 + 31507523 = 31507596
89 + 31507507 = 31507596
137 + 31507459 = 31507596
193 + 31507403 = 31507596

Showing the first eight; more decompositions exist.
