Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601712, here are decompositions:

5 + 31601707 = 31601712
13 + 31601699 = 31601712
41 + 31601671 = 31601712
61 + 31601651 = 31601712
83 + 31601629 = 31601712
173 + 31601539 = 31601712
199 + 31601513 = 31601712
223 + 31601489 = 31601712

Showing the first eight; more decompositions exist.
