Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668726, here are decompositions:

5 + 8668721 = 8668726
29 + 8668697 = 8668726
83 + 8668643 = 8668726
89 + 8668637 = 8668726
113 + 8668613 = 8668726
149 + 8668577 = 8668726
173 + 8668553 = 8668726
179 + 8668547 = 8668726

Showing the first eight; more decompositions exist.
