Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596270, here are decompositions:

61 + 31596209 = 31596270
107 + 31596163 = 31596270
127 + 31596143 = 31596270
149 + 31596121 = 31596270
151 + 31596119 = 31596270
229 + 31596041 = 31596270
241 + 31596029 = 31596270
263 + 31596007 = 31596270

Showing the first eight; more decompositions exist.
