Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601636, here are decompositions:

7 + 31601629 = 31601636
67 + 31601569 = 31601636
97 + 31601539 = 31601636
109 + 31601527 = 31601636
127 + 31601509 = 31601636
163 + 31601473 = 31601636
229 + 31601407 = 31601636
277 + 31601359 = 31601636

Showing the first eight; more decompositions exist.
