Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596434, here are decompositions:

31 + 31596403 = 31596434
43 + 31596391 = 31596434
127 + 31596307 = 31596434
241 + 31596193 = 31596434
271 + 31596163 = 31596434
283 + 31596151 = 31596434
307 + 31596127 = 31596434
313 + 31596121 = 31596434

Showing the first eight; more decompositions exist.
