Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514686, here are decompositions:

23 + 31514663 = 31514686
59 + 31514627 = 31514686
107 + 31514579 = 31514686
113 + 31514573 = 31514686
149 + 31514537 = 31514686
173 + 31514513 = 31514686
257 + 31514429 = 31514686
263 + 31514423 = 31514686

Showing the first eight; more decompositions exist.
