Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626696, here are decompositions:

5 + 31626691 = 31626696
7 + 31626689 = 31626696
29 + 31626667 = 31626696
89 + 31626607 = 31626696
107 + 31626589 = 31626696
139 + 31626557 = 31626696
149 + 31626547 = 31626696
163 + 31626533 = 31626696

Showing the first eight; more decompositions exist.
