Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660550, here are decompositions:

7 + 8660543 = 8660550
11 + 8660539 = 8660550
13 + 8660537 = 8660550
23 + 8660527 = 8660550
43 + 8660507 = 8660550
47 + 8660503 = 8660550
83 + 8660467 = 8660550
89 + 8660461 = 8660550

Showing the first eight; more decompositions exist.
