Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668784, here are decompositions:

43 + 8668741 = 8668784
73 + 8668711 = 8668784
97 + 8668687 = 8668784
283 + 8668501 = 8668784
577 + 8668207 = 8668784
643 + 8668141 = 8668784
673 + 8668111 = 8668784
727 + 8668057 = 8668784

Showing the first eight; more decompositions exist.
