Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463550, here are decompositions:

17 + 31463533 = 31463550
23 + 31463527 = 31463550
31 + 31463519 = 31463550
43 + 31463507 = 31463550
61 + 31463489 = 31463550
67 + 31463483 = 31463550
73 + 31463477 = 31463550
163 + 31463387 = 31463550

Showing the first eight; more decompositions exist.
