Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550460, here are decompositions:

13 + 31550447 = 31550460
23 + 31550437 = 31550460
59 + 31550401 = 31550460
89 + 31550371 = 31550460
103 + 31550357 = 31550460
107 + 31550353 = 31550460
131 + 31550329 = 31550460
173 + 31550287 = 31550460

Showing the first eight; more decompositions exist.
