Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668566, here are decompositions:

13 + 8668553 = 8668566
17 + 8668549 = 8668566
19 + 8668547 = 8668566
43 + 8668523 = 8668566
47 + 8668519 = 8668566
83 + 8668483 = 8668566
107 + 8668459 = 8668566
163 + 8668403 = 8668566

Showing the first eight; more decompositions exist.
