Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639586, here are decompositions:

19 + 8639567 = 8639586
23 + 8639563 = 8639586
37 + 8639549 = 8639586
47 + 8639539 = 8639586
79 + 8639507 = 8639586
127 + 8639459 = 8639586
173 + 8639413 = 8639586
223 + 8639363 = 8639586

Showing the first eight; more decompositions exist.
