Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656516, here are decompositions:

5 + 8656511 = 8656516
17 + 8656499 = 8656516
23 + 8656493 = 8656516
47 + 8656469 = 8656516
53 + 8656463 = 8656516
83 + 8656433 = 8656516
137 + 8656379 = 8656516
149 + 8656367 = 8656516

Showing the first eight; more decompositions exist.
