Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601512, here are decompositions:

3 + 31601509 = 31601512
23 + 31601489 = 31601512
101 + 31601411 = 31601512
461 + 31601051 = 31601512
653 + 31600859 = 31601512
809 + 31600703 = 31601512
983 + 31600529 = 31601512
1019 + 31600493 = 31601512

Showing the first eight; more decompositions exist.
