Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656586, here are decompositions:

13 + 8656573 = 8656586
109 + 8656477 = 8656586
163 + 8656423 = 8656586
193 + 8656393 = 8656586
223 + 8656363 = 8656586
229 + 8656357 = 8656586
307 + 8656279 = 8656586
313 + 8656273 = 8656586

Showing the first eight; more decompositions exist.
