Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626810, here are decompositions:

13 + 31626797 = 31626810
23 + 31626787 = 31626810
43 + 31626767 = 31626810
101 + 31626709 = 31626810
191 + 31626619 = 31626810
239 + 31626571 = 31626810
263 + 31626547 = 31626810
277 + 31626533 = 31626810

Showing the first eight; more decompositions exist.
