Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676728, here are decompositions:

7 + 8676721 = 8676728
37 + 8676691 = 8676728
97 + 8676631 = 8676728
127 + 8676601 = 8676728
211 + 8676517 = 8676728
241 + 8676487 = 8676728
331 + 8676397 = 8676728
367 + 8676361 = 8676728

Showing the first eight; more decompositions exist.
