Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659320, here are decompositions:

11 + 8659309 = 8659320
31 + 8659289 = 8659320
41 + 8659279 = 8659320
97 + 8659223 = 8659320
101 + 8659219 = 8659320
113 + 8659207 = 8659320
139 + 8659181 = 8659320
167 + 8659153 = 8659320

Showing the first eight; more decompositions exist.
