Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596138, here are decompositions:

11 + 31596127 = 31596138
17 + 31596121 = 31596138
19 + 31596119 = 31596138
71 + 31596067 = 31596138
89 + 31596049 = 31596138
97 + 31596041 = 31596138
109 + 31596029 = 31596138
131 + 31596007 = 31596138

Showing the first eight; more decompositions exist.
