Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668750, here are decompositions:

11 + 8668739 = 8668750
29 + 8668721 = 8668750
53 + 8668697 = 8668750
107 + 8668643 = 8668750
113 + 8668637 = 8668750
137 + 8668613 = 8668750
173 + 8668577 = 8668750
179 + 8668571 = 8668750

Showing the first eight; more decompositions exist.
