Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596118, here are decompositions:

89 + 31596029 = 31596118
149 + 31595969 = 31596118
251 + 31595867 = 31596118
311 + 31595807 = 31596118
347 + 31595771 = 31596118
401 + 31595717 = 31596118
431 + 31595687 = 31596118
461 + 31595657 = 31596118

Showing the first eight; more decompositions exist.
