Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596264, here are decompositions:

71 + 31596193 = 31596264
101 + 31596163 = 31596264
113 + 31596151 = 31596264
137 + 31596127 = 31596264
197 + 31596067 = 31596264
223 + 31596041 = 31596264
257 + 31596007 = 31596264
281 + 31595983 = 31596264

Showing the first eight; more decompositions exist.
