Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596276, here are decompositions:

67 + 31596209 = 31596276
83 + 31596193 = 31596276
113 + 31596163 = 31596276
149 + 31596127 = 31596276
157 + 31596119 = 31596276
227 + 31596049 = 31596276
269 + 31596007 = 31596276
293 + 31595983 = 31596276

Showing the first eight; more decompositions exist.
