Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463518, here are decompositions:

11 + 31463507 = 31463518
29 + 31463489 = 31463518
41 + 31463477 = 31463518
59 + 31463459 = 31463518
89 + 31463429 = 31463518
131 + 31463387 = 31463518
197 + 31463321 = 31463518
257 + 31463261 = 31463518

Showing the first eight; more decompositions exist.
