Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596154, here are decompositions:

3 + 31596151 = 31596154
11 + 31596143 = 31596154
113 + 31596041 = 31596154
281 + 31595873 = 31596154
347 + 31595807 = 31596154
383 + 31595771 = 31596154
431 + 31595723 = 31596154
467 + 31595687 = 31596154

Showing the first eight; more decompositions exist.
