Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668554, here are decompositions:

5 + 8668549 = 8668554
7 + 8668547 = 8668554
31 + 8668523 = 8668554
53 + 8668501 = 8668554
71 + 8668483 = 8668554
131 + 8668423 = 8668554
151 + 8668403 = 8668554
173 + 8668381 = 8668554

Showing the first eight; more decompositions exist.
