Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646586, here are decompositions:

5 + 8646581 = 8646586
83 + 8646503 = 8646586
89 + 8646497 = 8646586
107 + 8646479 = 8646586
197 + 8646389 = 8646586
257 + 8646329 = 8646586
269 + 8646317 = 8646586
293 + 8646293 = 8646586

Showing the first eight; more decompositions exist.
