Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624710, here are decompositions:

11 + 31624699 = 31624710
37 + 31624673 = 31624710
67 + 31624643 = 31624710
71 + 31624639 = 31624710
79 + 31624631 = 31624710
83 + 31624627 = 31624710
97 + 31624613 = 31624710
113 + 31624597 = 31624710

Showing the first eight; more decompositions exist.
