Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596126, here are decompositions:

5 + 31596121 = 31596126
7 + 31596119 = 31596126
59 + 31596067 = 31596126
97 + 31596029 = 31596126
137 + 31595989 = 31596126
157 + 31595969 = 31596126
197 + 31595929 = 31596126
257 + 31595869 = 31596126

Showing the first eight; more decompositions exist.
