Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483460, here are decompositions:

3 + 31483457 = 31483460
7 + 31483453 = 31483460
13 + 31483447 = 31483460
31 + 31483429 = 31483460
109 + 31483351 = 31483460
199 + 31483261 = 31483460
223 + 31483237 = 31483460
367 + 31483093 = 31483460

Showing the first eight; more decompositions exist.
