Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463610, here are decompositions:

19 + 31463591 = 31463610
23 + 31463587 = 31463610
83 + 31463527 = 31463610
103 + 31463507 = 31463610
127 + 31463483 = 31463610
151 + 31463459 = 31463610
181 + 31463429 = 31463610
223 + 31463387 = 31463610

Showing the first eight; more decompositions exist.
