Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507610, here are decompositions:

3 + 31507607 = 31507610
19 + 31507591 = 31507610
37 + 31507573 = 31507610
103 + 31507507 = 31507610
151 + 31507459 = 31507610
313 + 31507297 = 31507610
367 + 31507243 = 31507610
523 + 31507087 = 31507610

Showing the first eight; more decompositions exist.
