Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666504, here are decompositions:

3 + 8666501 = 8666504
13 + 8666491 = 8666504
61 + 8666443 = 8666504
73 + 8666431 = 8666504
157 + 8666347 = 8666504
181 + 8666323 = 8666504
331 + 8666173 = 8666504
337 + 8666167 = 8666504

Showing the first eight; more decompositions exist.
