Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659540, here are decompositions:

3 + 8659537 = 8659540
83 + 8659457 = 8659540
251 + 8659289 = 8659540
317 + 8659223 = 8659540
359 + 8659181 = 8659540
419 + 8659121 = 8659540
443 + 8659097 = 8659540
479 + 8659061 = 8659540

Showing the first eight; more decompositions exist.
