Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596188, here are decompositions:

37 + 31596151 = 31596188
61 + 31596127 = 31596188
67 + 31596121 = 31596188
139 + 31596049 = 31596188
181 + 31596007 = 31596188
199 + 31595989 = 31596188
307 + 31595881 = 31596188
457 + 31595731 = 31596188

Showing the first eight; more decompositions exist.
