Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666516, here are decompositions:

3 + 8666513 = 8666516
37 + 8666479 = 8666516
73 + 8666443 = 8666516
97 + 8666419 = 8666516
193 + 8666323 = 8666516
349 + 8666167 = 8666516
379 + 8666137 = 8666516
457 + 8666059 = 8666516

Showing the first eight; more decompositions exist.
