Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626682, here are decompositions:

149 + 31626533 = 31626682
293 + 31626389 = 31626682
359 + 31626323 = 31626682
449 + 31626233 = 31626682
491 + 31626191 = 31626682
641 + 31626041 = 31626682
701 + 31625981 = 31626682
719 + 31625963 = 31626682

Showing the first eight; more decompositions exist.
