Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627966, here are decompositions:

5 + 31627961 = 31627966
17 + 31627949 = 31627966
173 + 31627793 = 31627966
239 + 31627727 = 31627966
317 + 31627649 = 31627966
389 + 31627577 = 31627966
593 + 31627373 = 31627966
647 + 31627319 = 31627966

Showing the first eight; more decompositions exist.
