Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668528, here are decompositions:

5 + 8668523 = 8668528
107 + 8668421 = 8668528
149 + 8668379 = 8668528
179 + 8668349 = 8668528
227 + 8668301 = 8668528
461 + 8668067 = 8668528
467 + 8668061 = 8668528
599 + 8667929 = 8668528

Showing the first eight; more decompositions exist.
