Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689778, here are decompositions:

67 + 8689711 = 8689778
151 + 8689627 = 8689778
241 + 8689537 = 8689778
379 + 8689399 = 8689778
457 + 8689321 = 8689778
499 + 8689279 = 8689778
709 + 8689069 = 8689778
739 + 8689039 = 8689778

Showing the first eight; more decompositions exist.
