Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596050, here are decompositions:

43 + 31596007 = 31596050
61 + 31595989 = 31596050
67 + 31595983 = 31596050
181 + 31595869 = 31596050
331 + 31595719 = 31596050
349 + 31595701 = 31596050
379 + 31595671 = 31596050
397 + 31595653 = 31596050

Showing the first eight; more decompositions exist.
