Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628672, here are decompositions:

11 + 8628661 = 8628672
29 + 8628643 = 8628672
43 + 8628629 = 8628672
71 + 8628601 = 8628672
179 + 8628493 = 8628672
191 + 8628481 = 8628672
193 + 8628479 = 8628672
223 + 8628449 = 8628672

Showing the first eight; more decompositions exist.
