Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626610, here are decompositions:

3 + 31626607 = 31626610
47 + 31626563 = 31626610
53 + 31626557 = 31626610
149 + 31626461 = 31626610
173 + 31626437 = 31626610
227 + 31626383 = 31626610
233 + 31626377 = 31626610
251 + 31626359 = 31626610

Showing the first eight; more decompositions exist.
