Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666496, here are decompositions:

5 + 8666491 = 8666496
17 + 8666479 = 8666496
19 + 8666477 = 8666496
37 + 8666459 = 8666496
53 + 8666443 = 8666496
79 + 8666417 = 8666496
103 + 8666393 = 8666496
109 + 8666387 = 8666496

Showing the first eight; more decompositions exist.
