Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666604, here are decompositions:

7 + 8666597 = 8666604
13 + 8666591 = 8666604
61 + 8666543 = 8666604
71 + 8666533 = 8666604
103 + 8666501 = 8666604
113 + 8666491 = 8666604
127 + 8666477 = 8666604
173 + 8666431 = 8666604

Showing the first eight; more decompositions exist.
