Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626456, here are decompositions:

19 + 31626437 = 31626456
67 + 31626389 = 31626456
73 + 31626383 = 31626456
79 + 31626377 = 31626456
89 + 31626367 = 31626456
97 + 31626359 = 31626456
223 + 31626233 = 31626456
227 + 31626229 = 31626456

Showing the first eight; more decompositions exist.
