Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666618, here are decompositions:

127 + 8666491 = 8666618
139 + 8666479 = 8666618
199 + 8666419 = 8666618
271 + 8666347 = 8666618
349 + 8666269 = 8666618
601 + 8666017 = 8666618
619 + 8665999 = 8666618
769 + 8665849 = 8666618

Showing the first eight; more decompositions exist.
