Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659398, here are decompositions:

5 + 8659393 = 8659398
17 + 8659381 = 8659398
47 + 8659351 = 8659398
89 + 8659309 = 8659398
109 + 8659289 = 8659398
179 + 8659219 = 8659398
191 + 8659207 = 8659398
277 + 8659121 = 8659398

Showing the first eight; more decompositions exist.
