Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508294, here are decompositions:

7 + 31508287 = 31508294
61 + 31508233 = 31508294
67 + 31508227 = 31508294
151 + 31508143 = 31508294
193 + 31508101 = 31508294
211 + 31508083 = 31508294
277 + 31508017 = 31508294
313 + 31507981 = 31508294

Showing the first eight; more decompositions exist.
