Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659518, here are decompositions:

5 + 8659513 = 8659518
17 + 8659501 = 8659518
47 + 8659471 = 8659518
61 + 8659457 = 8659518
137 + 8659381 = 8659518
167 + 8659351 = 8659518
229 + 8659289 = 8659518
239 + 8659279 = 8659518

Showing the first eight; more decompositions exist.
