Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622914, here are decompositions:

137 + 31622777 = 31622914
173 + 31622741 = 31622914
227 + 31622687 = 31622914
251 + 31622663 = 31622914
641 + 31622273 = 31622914
677 + 31622237 = 31622914
761 + 31622153 = 31622914
773 + 31622141 = 31622914

Showing the first eight; more decompositions exist.
