Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624856, here are decompositions:

7 + 31624849 = 31624856
19 + 31624837 = 31624856
73 + 31624783 = 31624856
103 + 31624753 = 31624856
139 + 31624717 = 31624856
157 + 31624699 = 31624856
229 + 31624627 = 31624856
349 + 31624507 = 31624856

Showing the first eight; more decompositions exist.
