Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602212, here are decompositions:

163 + 31602049 = 31602212
331 + 31601881 = 31602212
349 + 31601863 = 31602212
541 + 31601671 = 31602212
643 + 31601569 = 31602212
661 + 31601551 = 31602212
673 + 31601539 = 31602212
739 + 31601473 = 31602212

Showing the first eight; more decompositions exist.
