Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668556, here are decompositions:

3 + 8668553 = 8668556
7 + 8668549 = 8668556
37 + 8668519 = 8668556
67 + 8668489 = 8668556
73 + 8668483 = 8668556
97 + 8668459 = 8668556
199 + 8668357 = 8668556
277 + 8668279 = 8668556

Showing the first eight; more decompositions exist.
