Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596312, here are decompositions:

5 + 31596307 = 31596312
19 + 31596293 = 31596312
103 + 31596209 = 31596312
149 + 31596163 = 31596312
191 + 31596121 = 31596312
193 + 31596119 = 31596312
263 + 31596049 = 31596312
271 + 31596041 = 31596312

Showing the first eight; more decompositions exist.
