Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596470, here are decompositions:

67 + 31596403 = 31596470
79 + 31596391 = 31596470
163 + 31596307 = 31596470
277 + 31596193 = 31596470
307 + 31596163 = 31596470
349 + 31596121 = 31596470
421 + 31596049 = 31596470
463 + 31596007 = 31596470

Showing the first eight; more decompositions exist.
