Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627462, here are decompositions:

71 + 31627391 = 31627462
89 + 31627373 = 31627462
173 + 31627289 = 31627462
311 + 31627151 = 31627462
389 + 31627073 = 31627462
563 + 31626899 = 31627462
569 + 31626893 = 31627462
593 + 31626869 = 31627462

Showing the first eight; more decompositions exist.
