Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631668, here are decompositions:

151 + 8631517 = 8631668
277 + 8631391 = 8631668
337 + 8631331 = 8631668
349 + 8631319 = 8631668
421 + 8631247 = 8631668
439 + 8631229 = 8631668
571 + 8631097 = 8631668
631 + 8631037 = 8631668

Showing the first eight; more decompositions exist.
