Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660508, here are decompositions:

5 + 8660503 = 8660508
41 + 8660467 = 8660508
47 + 8660461 = 8660508
71 + 8660437 = 8660508
89 + 8660419 = 8660508
107 + 8660401 = 8660508
127 + 8660381 = 8660508
139 + 8660369 = 8660508

Showing the first eight; more decompositions exist.
