Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596258, here are decompositions:

107 + 31596151 = 31596258
131 + 31596127 = 31596258
137 + 31596121 = 31596258
139 + 31596119 = 31596258
191 + 31596067 = 31596258
229 + 31596029 = 31596258
251 + 31596007 = 31596258
269 + 31595989 = 31596258

Showing the first eight; more decompositions exist.
