Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463844, here are decompositions:

17 + 31463827 = 31463844
37 + 31463807 = 31463844
47 + 31463797 = 31463844
101 + 31463743 = 31463844
127 + 31463717 = 31463844
131 + 31463713 = 31463844
163 + 31463681 = 31463844
257 + 31463587 = 31463844

Showing the first eight; more decompositions exist.
