Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463766, here are decompositions:

7 + 31463759 = 31463766
23 + 31463743 = 31463766
53 + 31463713 = 31463766
179 + 31463587 = 31463766
233 + 31463533 = 31463766
239 + 31463527 = 31463766
277 + 31463489 = 31463766
283 + 31463483 = 31463766

Showing the first eight; more decompositions exist.
