Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601688, here are decompositions:

17 + 31601671 = 31601688
37 + 31601651 = 31601688
59 + 31601629 = 31601688
137 + 31601551 = 31601688
149 + 31601539 = 31601688
179 + 31601509 = 31601688
199 + 31601489 = 31601688
271 + 31601417 = 31601688

Showing the first eight; more decompositions exist.
