Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666684, here are decompositions:

3 + 8666681 = 8666684
151 + 8666533 = 8666684
193 + 8666491 = 8666684
241 + 8666443 = 8666684
337 + 8666347 = 8666684
547 + 8666137 = 8666684
661 + 8666023 = 8666684
751 + 8665933 = 8666684

Showing the first eight; more decompositions exist.
