Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666508, here are decompositions:

7 + 8666501 = 8666508
17 + 8666491 = 8666508
29 + 8666479 = 8666508
31 + 8666477 = 8666508
89 + 8666419 = 8666508
127 + 8666381 = 8666508
139 + 8666369 = 8666508
157 + 8666351 = 8666508

Showing the first eight; more decompositions exist.
