Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624806, here are decompositions:

7 + 31624799 = 31624806
23 + 31624783 = 31624806
43 + 31624763 = 31624806
53 + 31624753 = 31624806
67 + 31624739 = 31624806
89 + 31624717 = 31624806
107 + 31624699 = 31624806
163 + 31624643 = 31624806

Showing the first eight; more decompositions exist.
