Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626708, here are decompositions:

17 + 31626691 = 31626708
19 + 31626689 = 31626708
41 + 31626667 = 31626708
89 + 31626619 = 31626708
101 + 31626607 = 31626708
137 + 31626571 = 31626708
151 + 31626557 = 31626708
227 + 31626481 = 31626708

Showing the first eight; more decompositions exist.
