Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514650, here are decompositions:

23 + 31514627 = 31514650
71 + 31514579 = 31514650
113 + 31514537 = 31514650
137 + 31514513 = 31514650
173 + 31514477 = 31514650
227 + 31514423 = 31514650
353 + 31514297 = 31514650
359 + 31514291 = 31514650

Showing the first eight; more decompositions exist.
