Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626616, here are decompositions:

53 + 31626563 = 31626616
59 + 31626557 = 31626616
83 + 31626533 = 31626616
179 + 31626437 = 31626616
227 + 31626389 = 31626616
233 + 31626383 = 31626616
239 + 31626377 = 31626616
257 + 31626359 = 31626616

Showing the first eight; more decompositions exist.
