Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624896, here are decompositions:

47 + 31624849 = 31624896
59 + 31624837 = 31624896
67 + 31624829 = 31624896
89 + 31624807 = 31624896
97 + 31624799 = 31624896
113 + 31624783 = 31624896
157 + 31624739 = 31624896
179 + 31624717 = 31624896

Showing the first eight; more decompositions exist.
