Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628636, here are decompositions:

7 + 8628629 = 8628636
13 + 8628623 = 8628636
83 + 8628553 = 8628636
89 + 8628547 = 8628636
157 + 8628479 = 8628636
173 + 8628463 = 8628636
193 + 8628443 = 8628636
229 + 8628407 = 8628636

Showing the first eight; more decompositions exist.
