Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668690, here are decompositions:

3 + 8668687 = 8668690
47 + 8668643 = 8668690
53 + 8668637 = 8668690
113 + 8668577 = 8668690
137 + 8668553 = 8668690
167 + 8668523 = 8668690
269 + 8668421 = 8668690
311 + 8668379 = 8668690

Showing the first eight; more decompositions exist.
