Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659720, here are decompositions:

29 + 8659691 = 8659720
53 + 8659667 = 8659720
89 + 8659631 = 8659720
131 + 8659589 = 8659720
257 + 8659463 = 8659720
263 + 8659457 = 8659720
431 + 8659289 = 8659720
599 + 8659121 = 8659720

Showing the first eight; more decompositions exist.
