Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605566, here are decompositions:

5 + 8605561 = 8605566
23 + 8605543 = 8605566
37 + 8605529 = 8605566
97 + 8605469 = 8605566
103 + 8605463 = 8605566
163 + 8605403 = 8605566
197 + 8605369 = 8605566
269 + 8605297 = 8605566

Showing the first eight; more decompositions exist.
