Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660556, here are decompositions:

13 + 8660543 = 8660556
17 + 8660539 = 8660556
19 + 8660537 = 8660556
29 + 8660527 = 8660556
53 + 8660503 = 8660556
89 + 8660467 = 8660556
137 + 8660419 = 8660556
173 + 8660383 = 8660556

Showing the first eight; more decompositions exist.
