Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601736, here are decompositions:

13 + 31601723 = 31601736
29 + 31601707 = 31601736
37 + 31601699 = 31601736
107 + 31601629 = 31601736
167 + 31601569 = 31601736
197 + 31601539 = 31601736
223 + 31601513 = 31601736
227 + 31601509 = 31601736

Showing the first eight; more decompositions exist.
