Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626698, here are decompositions:

7 + 31626691 = 31626698
31 + 31626667 = 31626698
79 + 31626619 = 31626698
109 + 31626589 = 31626698
127 + 31626571 = 31626698
151 + 31626547 = 31626698
199 + 31626499 = 31626698
277 + 31626421 = 31626698

Showing the first eight; more decompositions exist.
