Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668786, here are decompositions:

3 + 8668783 = 8668786
23 + 8668763 = 8668786
47 + 8668739 = 8668786
89 + 8668697 = 8668786
149 + 8668637 = 8668786
173 + 8668613 = 8668786
233 + 8668553 = 8668786
239 + 8668547 = 8668786

Showing the first eight; more decompositions exist.
