Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668788, here are decompositions:

5 + 8668783 = 8668788
47 + 8668741 = 8668788
67 + 8668721 = 8668788
101 + 8668687 = 8668788
151 + 8668637 = 8668788
179 + 8668609 = 8668788
211 + 8668577 = 8668788
239 + 8668549 = 8668788

Showing the first eight; more decompositions exist.
