Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659386, here are decompositions:

5 + 8659381 = 8659386
23 + 8659363 = 8659386
97 + 8659289 = 8659386
107 + 8659279 = 8659386
163 + 8659223 = 8659386
167 + 8659219 = 8659386
179 + 8659207 = 8659386
233 + 8659153 = 8659386

Showing the first eight; more decompositions exist.
