Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626670, here are decompositions:

3 + 31626667 = 31626670
107 + 31626563 = 31626670
113 + 31626557 = 31626670
137 + 31626533 = 31626670
233 + 31626437 = 31626670
263 + 31626407 = 31626670
281 + 31626389 = 31626670
293 + 31626377 = 31626670

Showing the first eight; more decompositions exist.
