Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596320, here are decompositions:

3 + 31596317 = 31596320
13 + 31596307 = 31596320
127 + 31596193 = 31596320
157 + 31596163 = 31596320
193 + 31596127 = 31596320
199 + 31596121 = 31596320
271 + 31596049 = 31596320
313 + 31596007 = 31596320

Showing the first eight; more decompositions exist.
