Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624914, here are decompositions:

7 + 31624907 = 31624914
53 + 31624861 = 31624914
107 + 31624807 = 31624914
131 + 31624783 = 31624914
151 + 31624763 = 31624914
173 + 31624741 = 31624914
197 + 31624717 = 31624914
241 + 31624673 = 31624914

Showing the first eight; more decompositions exist.
