Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601522, here are decompositions:

13 + 31601509 = 31601522
163 + 31601359 = 31601522
181 + 31601341 = 31601522
331 + 31601191 = 31601522
439 + 31601083 = 31601522
499 + 31601023 = 31601522
661 + 31600861 = 31601522
739 + 31600783 = 31601522

Showing the first eight; more decompositions exist.
