Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596132, here are decompositions:

5 + 31596127 = 31596132
11 + 31596121 = 31596132
13 + 31596119 = 31596132
83 + 31596049 = 31596132
103 + 31596029 = 31596132
149 + 31595983 = 31596132
163 + 31595969 = 31596132
251 + 31595881 = 31596132

Showing the first eight; more decompositions exist.
