Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596366, here are decompositions:

59 + 31596307 = 31596366
73 + 31596293 = 31596366
157 + 31596209 = 31596366
173 + 31596193 = 31596366
223 + 31596143 = 31596366
239 + 31596127 = 31596366
317 + 31596049 = 31596366
337 + 31596029 = 31596366

Showing the first eight; more decompositions exist.
