Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659778, here are decompositions:

31 + 8659747 = 8659778
37 + 8659741 = 8659778
67 + 8659711 = 8659778
109 + 8659669 = 8659778
151 + 8659627 = 8659778
241 + 8659537 = 8659778
277 + 8659501 = 8659778
307 + 8659471 = 8659778

Showing the first eight; more decompositions exist.
