Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626722, here are decompositions:

13 + 31626709 = 31626722
31 + 31626691 = 31626722
103 + 31626619 = 31626722
151 + 31626571 = 31626722
223 + 31626499 = 31626722
229 + 31626493 = 31626722
241 + 31626481 = 31626722
613 + 31626109 = 31626722

Showing the first eight; more decompositions exist.
