Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659780, here are decompositions:

11 + 8659769 = 8659780
89 + 8659691 = 8659780
113 + 8659667 = 8659780
137 + 8659643 = 8659780
149 + 8659631 = 8659780
179 + 8659601 = 8659780
191 + 8659589 = 8659780
317 + 8659463 = 8659780

Showing the first eight; more decompositions exist.
