Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666654, here are decompositions:

163 + 8666491 = 8666654
211 + 8666443 = 8666654
223 + 8666431 = 8666654
307 + 8666347 = 8666654
331 + 8666323 = 8666654
487 + 8666167 = 8666654
631 + 8666023 = 8666654
757 + 8665897 = 8666654

Showing the first eight; more decompositions exist.
