Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596150, here are decompositions:

7 + 31596143 = 31596150
23 + 31596127 = 31596150
29 + 31596121 = 31596150
31 + 31596119 = 31596150
83 + 31596067 = 31596150
101 + 31596049 = 31596150
109 + 31596041 = 31596150
167 + 31595983 = 31596150

Showing the first eight; more decompositions exist.
