Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621508, here are decompositions:

17 + 8621491 = 8621508
29 + 8621479 = 8621508
31 + 8621477 = 8621508
41 + 8621467 = 8621508
79 + 8621429 = 8621508
97 + 8621411 = 8621508
131 + 8621377 = 8621508
199 + 8621309 = 8621508

Showing the first eight; more decompositions exist.
