Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624776, here are decompositions:

13 + 31624763 = 31624776
23 + 31624753 = 31624776
37 + 31624739 = 31624776
59 + 31624717 = 31624776
103 + 31624673 = 31624776
137 + 31624639 = 31624776
149 + 31624627 = 31624776
163 + 31624613 = 31624776

Showing the first eight; more decompositions exist.
