Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596360, here are decompositions:

43 + 31596317 = 31596360
53 + 31596307 = 31596360
67 + 31596293 = 31596360
151 + 31596209 = 31596360
167 + 31596193 = 31596360
197 + 31596163 = 31596360
233 + 31596127 = 31596360
239 + 31596121 = 31596360

Showing the first eight; more decompositions exist.
