Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450552, here are decompositions:

11 + 31450541 = 31450552
101 + 31450451 = 31450552
131 + 31450421 = 31450552
239 + 31450313 = 31450552
281 + 31450271 = 31450552
389 + 31450163 = 31450552
449 + 31450103 = 31450552
491 + 31450061 = 31450552

Showing the first eight; more decompositions exist.
