Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626622, here are decompositions:

3 + 31626619 = 31626622
59 + 31626563 = 31626622
89 + 31626533 = 31626622
233 + 31626389 = 31626622
239 + 31626383 = 31626622
263 + 31626359 = 31626622
389 + 31626233 = 31626622
431 + 31626191 = 31626622

Showing the first eight; more decompositions exist.
