Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608294, here are decompositions:

23 + 31608271 = 31608294
31 + 31608263 = 31608294
127 + 31608167 = 31608294
131 + 31608163 = 31608294
163 + 31608131 = 31608294
227 + 31608067 = 31608294
233 + 31608061 = 31608294
257 + 31608037 = 31608294

Showing the first eight; more decompositions exist.
