Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668018, here are decompositions:

17 + 8668001 = 8668018
89 + 8667929 = 8668018
197 + 8667821 = 8668018
311 + 8667707 = 8668018
479 + 8667539 = 8668018
521 + 8667497 = 8668018
587 + 8667431 = 8668018
599 + 8667419 = 8668018

Showing the first eight; more decompositions exist.
