Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626406, here are decompositions:

17 + 31626389 = 31626406
23 + 31626383 = 31626406
29 + 31626377 = 31626406
47 + 31626359 = 31626406
83 + 31626323 = 31626406
173 + 31626233 = 31626406
197 + 31626209 = 31626406
239 + 31626167 = 31626406

Showing the first eight; more decompositions exist.
