Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508484, here are decompositions:

23 + 31508461 = 31508484
31 + 31508453 = 31508484
41 + 31508443 = 31508484
67 + 31508417 = 31508484
173 + 31508311 = 31508484
197 + 31508287 = 31508484
251 + 31508233 = 31508484
257 + 31508227 = 31508484

Showing the first eight; more decompositions exist.
