Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596468, here are decompositions:

31 + 31596437 = 31596468
67 + 31596401 = 31596468
89 + 31596379 = 31596468
151 + 31596317 = 31596468
157 + 31596311 = 31596468
317 + 31596151 = 31596468
347 + 31596121 = 31596468
349 + 31596119 = 31596468

Showing the first eight; more decompositions exist.
