Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463634, here are decompositions:

43 + 31463591 = 31463634
47 + 31463587 = 31463634
101 + 31463533 = 31463634
107 + 31463527 = 31463634
127 + 31463507 = 31463634
151 + 31463483 = 31463634
157 + 31463477 = 31463634
227 + 31463407 = 31463634

Showing the first eight; more decompositions exist.
