Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624766, here are decompositions:

3 + 31624763 = 31624766
13 + 31624753 = 31624766
67 + 31624699 = 31624766
127 + 31624639 = 31624766
139 + 31624627 = 31624766
337 + 31624429 = 31624766
379 + 31624387 = 31624766
409 + 31624357 = 31624766

Showing the first eight; more decompositions exist.
