Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668988, here are decompositions:

37 + 8668951 = 8668988
151 + 8668837 = 8668988
157 + 8668831 = 8668988
277 + 8668711 = 8668988
379 + 8668609 = 8668988
439 + 8668549 = 8668988
487 + 8668501 = 8668988
499 + 8668489 = 8668988

Showing the first eight; more decompositions exist.
