Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668780, here are decompositions:

17 + 8668763 = 8668780
41 + 8668739 = 8668780
59 + 8668721 = 8668780
83 + 8668697 = 8668780
137 + 8668643 = 8668780
167 + 8668613 = 8668780
227 + 8668553 = 8668780
233 + 8668547 = 8668780

Showing the first eight; more decompositions exist.
