Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516360, here are decompositions:

3 + 31516357 = 31516360
41 + 31516319 = 31516360
107 + 31516253 = 31516360
251 + 31516109 = 31516360
257 + 31516103 = 31516360
353 + 31516007 = 31516360
419 + 31515941 = 31516360
461 + 31515899 = 31516360

Showing the first eight; more decompositions exist.
