Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514262, here are decompositions:

23 + 31514239 = 31514262
41 + 31514221 = 31514262
71 + 31514191 = 31514262
103 + 31514159 = 31514262
113 + 31514149 = 31514262
149 + 31514113 = 31514262
181 + 31514081 = 31514262
239 + 31514023 = 31514262

Showing the first eight; more decompositions exist.
