Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463672, here are decompositions:

139 + 31463533 = 31463672
283 + 31463389 = 31463672
739 + 31462933 = 31463672
1063 + 31462609 = 31463672
1069 + 31462603 = 31463672
1093 + 31462579 = 31463672
1201 + 31462471 = 31463672
1231 + 31462441 = 31463672

Showing the first eight; more decompositions exist.
