Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532182, here are decompositions:

41 + 31532141 = 31532182
179 + 31532003 = 31532182
251 + 31531931 = 31532182
431 + 31531751 = 31532182
503 + 31531679 = 31532182
659 + 31531523 = 31532182
761 + 31531421 = 31532182
881 + 31531301 = 31532182

Showing the first eight; more decompositions exist.
