Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463590, here are decompositions:

3 + 31463587 = 31463590
71 + 31463519 = 31463590
83 + 31463507 = 31463590
101 + 31463489 = 31463590
107 + 31463483 = 31463590
113 + 31463477 = 31463590
131 + 31463459 = 31463590
227 + 31463363 = 31463590

Showing the first eight; more decompositions exist.
