Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596306, here are decompositions:

13 + 31596293 = 31596306
97 + 31596209 = 31596306
113 + 31596193 = 31596306
163 + 31596143 = 31596306
179 + 31596127 = 31596306
239 + 31596067 = 31596306
257 + 31596049 = 31596306
277 + 31596029 = 31596306

Showing the first eight; more decompositions exist.
