Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608422, here are decompositions:

73 + 31608349 = 31608422
103 + 31608319 = 31608422
151 + 31608271 = 31608422
331 + 31608091 = 31608422
409 + 31608013 = 31608422
631 + 31607791 = 31608422
733 + 31607689 = 31608422
739 + 31607683 = 31608422

Showing the first eight; more decompositions exist.
