Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596146, here are decompositions:

3 + 31596143 = 31596146
19 + 31596127 = 31596146
79 + 31596067 = 31596146
97 + 31596049 = 31596146
139 + 31596007 = 31596146
157 + 31595989 = 31596146
163 + 31595983 = 31596146
277 + 31595869 = 31596146

Showing the first eight; more decompositions exist.
