Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628668, here are decompositions:

7 + 8628661 = 8628668
67 + 8628601 = 8628668
397 + 8628271 = 8628668
487 + 8628181 = 8628668
547 + 8628121 = 8628668
571 + 8628097 = 8628668
619 + 8628049 = 8628668
661 + 8628007 = 8628668

Showing the first eight; more decompositions exist.
