Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659784, here are decompositions:

37 + 8659747 = 8659784
43 + 8659741 = 8659784
73 + 8659711 = 8659784
157 + 8659627 = 8659784
241 + 8659543 = 8659784
271 + 8659513 = 8659784
283 + 8659501 = 8659784
313 + 8659471 = 8659784

Showing the first eight; more decompositions exist.
