Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626646, here are decompositions:

83 + 31626563 = 31626646
89 + 31626557 = 31626646
113 + 31626533 = 31626646
239 + 31626407 = 31626646
257 + 31626389 = 31626646
263 + 31626383 = 31626646
269 + 31626377 = 31626646
449 + 31626197 = 31626646

Showing the first eight; more decompositions exist.
