Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663566, here are decompositions:

29 + 8663537 = 8663566
47 + 8663519 = 8663566
59 + 8663507 = 8663566
257 + 8663309 = 8663566
293 + 8663273 = 8663566
449 + 8663117 = 8663566
467 + 8663099 = 8663566
563 + 8663003 = 8663566

Showing the first eight; more decompositions exist.
