Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463722, here are decompositions:

5 + 31463717 = 31463722
41 + 31463681 = 31463722
131 + 31463591 = 31463722
233 + 31463489 = 31463722
239 + 31463483 = 31463722
263 + 31463459 = 31463722
293 + 31463429 = 31463722
359 + 31463363 = 31463722

Showing the first eight; more decompositions exist.
