Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668666, here are decompositions:

23 + 8668643 = 8668666
29 + 8668637 = 8668666
53 + 8668613 = 8668666
89 + 8668577 = 8668666
113 + 8668553 = 8668666
263 + 8668403 = 8668666
317 + 8668349 = 8668666
509 + 8668157 = 8668666

Showing the first eight; more decompositions exist.
