Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621514, here are decompositions:

23 + 8621491 = 8621514
37 + 8621477 = 8621514
47 + 8621467 = 8621514
61 + 8621453 = 8621514
71 + 8621443 = 8621514
101 + 8621413 = 8621514
103 + 8621411 = 8621514
137 + 8621377 = 8621514

Showing the first eight; more decompositions exist.
