Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508196, here are decompositions:

17 + 31508179 = 31508196
19 + 31508177 = 31508196
37 + 31508159 = 31508196
43 + 31508153 = 31508196
53 + 31508143 = 31508196
89 + 31508107 = 31508196
103 + 31508093 = 31508196
113 + 31508083 = 31508196

Showing the first eight; more decompositions exist.
