Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659488, here are decompositions:

17 + 8659471 = 8659488
31 + 8659457 = 8659488
107 + 8659381 = 8659488
137 + 8659351 = 8659488
179 + 8659309 = 8659488
199 + 8659289 = 8659488
269 + 8659219 = 8659488
281 + 8659207 = 8659488

Showing the first eight; more decompositions exist.
