Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450414, here are decompositions:

3 + 31450411 = 31450414
5 + 31450409 = 31450414
101 + 31450313 = 31450414
167 + 31450247 = 31450414
197 + 31450217 = 31450414
251 + 31450163 = 31450414
311 + 31450103 = 31450414
353 + 31450061 = 31450414

Showing the first eight; more decompositions exist.
