Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668776, here are decompositions:

13 + 8668763 = 8668776
37 + 8668739 = 8668776
79 + 8668697 = 8668776
89 + 8668687 = 8668776
139 + 8668637 = 8668776
163 + 8668613 = 8668776
167 + 8668609 = 8668776
199 + 8668577 = 8668776

Showing the first eight; more decompositions exist.
