Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463238, here are decompositions:

11 + 31463227 = 31463238
41 + 31463197 = 31463238
71 + 31463167 = 31463238
101 + 31463137 = 31463238
139 + 31463099 = 31463238
151 + 31463087 = 31463238
269 + 31462969 = 31463238
307 + 31462931 = 31463238

Showing the first eight; more decompositions exist.
