Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626664, here are decompositions:

101 + 31626563 = 31626664
107 + 31626557 = 31626664
131 + 31626533 = 31626664
227 + 31626437 = 31626664
257 + 31626407 = 31626664
281 + 31626383 = 31626664
431 + 31626233 = 31626664
467 + 31626197 = 31626664

Showing the first eight; more decompositions exist.
