Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601692, here are decompositions:

41 + 31601651 = 31601692
179 + 31601513 = 31601692
281 + 31601411 = 31601692
593 + 31601099 = 31601692
641 + 31601051 = 31601692
809 + 31600883 = 31601692
971 + 31600721 = 31601692
1163 + 31600529 = 31601692

Showing the first eight; more decompositions exist.
