Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601762, here are decompositions:

19 + 31601743 = 31601762
193 + 31601569 = 31601762
211 + 31601551 = 31601762
223 + 31601539 = 31601762
421 + 31601341 = 31601762
499 + 31601263 = 31601762
571 + 31601191 = 31601762
739 + 31601023 = 31601762

Showing the first eight; more decompositions exist.
