Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628822, here are decompositions:

11 + 8628811 = 8628822
23 + 8628799 = 8628822
31 + 8628791 = 8628822
43 + 8628779 = 8628822
71 + 8628751 = 8628822
113 + 8628709 = 8628822
179 + 8628643 = 8628822
193 + 8628629 = 8628822

Showing the first eight; more decompositions exist.
