Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659380, here are decompositions:

17 + 8659363 = 8659380
29 + 8659351 = 8659380
71 + 8659309 = 8659380
101 + 8659279 = 8659380
137 + 8659243 = 8659380
157 + 8659223 = 8659380
173 + 8659207 = 8659380
199 + 8659181 = 8659380

Showing the first eight; more decompositions exist.
