Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508366, here are decompositions:

3 + 31508363 = 31508366
7 + 31508359 = 31508366
37 + 31508329 = 31508366
79 + 31508287 = 31508366
139 + 31508227 = 31508366
163 + 31508203 = 31508366
223 + 31508143 = 31508366
283 + 31508083 = 31508366

Showing the first eight; more decompositions exist.
