Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624764, here are decompositions:

11 + 31624753 = 31624764
23 + 31624741 = 31624764
47 + 31624717 = 31624764
103 + 31624661 = 31624764
137 + 31624627 = 31624764
151 + 31624613 = 31624764
167 + 31624597 = 31624764
173 + 31624591 = 31624764

Showing the first eight; more decompositions exist.
