Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596186, here are decompositions:

23 + 31596163 = 31596186
43 + 31596143 = 31596186
59 + 31596127 = 31596186
67 + 31596119 = 31596186
137 + 31596049 = 31596186
157 + 31596029 = 31596186
179 + 31596007 = 31596186
197 + 31595989 = 31596186

Showing the first eight; more decompositions exist.
