Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596162, here are decompositions:

11 + 31596151 = 31596162
19 + 31596143 = 31596162
41 + 31596121 = 31596162
43 + 31596119 = 31596162
113 + 31596049 = 31596162
173 + 31595989 = 31596162
179 + 31595983 = 31596162
193 + 31595969 = 31596162

Showing the first eight; more decompositions exist.
