Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666624, here are decompositions:

181 + 8666443 = 8666624
193 + 8666431 = 8666624
277 + 8666347 = 8666624
457 + 8666167 = 8666624
487 + 8666137 = 8666624
601 + 8666023 = 8666624
607 + 8666017 = 8666624
691 + 8665933 = 8666624

Showing the first eight; more decompositions exist.
