Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624758, here are decompositions:

5 + 31624753 = 31624758
17 + 31624741 = 31624758
19 + 31624739 = 31624758
41 + 31624717 = 31624758
59 + 31624699 = 31624758
97 + 31624661 = 31624758
127 + 31624631 = 31624758
131 + 31624627 = 31624758

Showing the first eight; more decompositions exist.
