Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599422, here are decompositions:

73 + 31599349 = 31599422
109 + 31599313 = 31599422
163 + 31599259 = 31599422
229 + 31599193 = 31599422
433 + 31598989 = 31599422
499 + 31598923 = 31599422
643 + 31598779 = 31599422
739 + 31598683 = 31599422

Showing the first eight; more decompositions exist.
