Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463560, here are decompositions:

41 + 31463519 = 31463560
53 + 31463507 = 31463560
71 + 31463489 = 31463560
83 + 31463477 = 31463560
101 + 31463459 = 31463560
131 + 31463429 = 31463560
173 + 31463387 = 31463560
197 + 31463363 = 31463560

Showing the first eight; more decompositions exist.
