Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628674, here are decompositions:

13 + 8628661 = 8628674
31 + 8628643 = 8628674
73 + 8628601 = 8628674
127 + 8628547 = 8628674
181 + 8628493 = 8628674
193 + 8628481 = 8628674
211 + 8628463 = 8628674
487 + 8628187 = 8628674

Showing the first eight; more decompositions exist.
