Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663556, here are decompositions:

19 + 8663537 = 8663556
37 + 8663519 = 8663556
47 + 8663509 = 8663556
53 + 8663503 = 8663556
59 + 8663497 = 8663556
89 + 8663467 = 8663556
199 + 8663357 = 8663556
277 + 8663279 = 8663556

Showing the first eight; more decompositions exist.
