Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628512, here are decompositions:

19 + 8628493 = 8628512
31 + 8628481 = 8628512
163 + 8628349 = 8628512
241 + 8628271 = 8628512
331 + 8628181 = 8628512
463 + 8628049 = 8628512
601 + 8627911 = 8628512
619 + 8627893 = 8628512

Showing the first eight; more decompositions exist.
