Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516468, here are decompositions:

41 + 31516427 = 31516468
89 + 31516379 = 31516468
107 + 31516361 = 31516468
149 + 31516319 = 31516468
227 + 31516241 = 31516468
311 + 31516157 = 31516468
359 + 31516109 = 31516468
461 + 31516007 = 31516468

Showing the first eight; more decompositions exist.
