Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628712, here are decompositions:

3 + 8628709 = 8628712
83 + 8628629 = 8628712
89 + 8628623 = 8628712
233 + 8628479 = 8628712
263 + 8628449 = 8628712
269 + 8628443 = 8628712
353 + 8628359 = 8628712
359 + 8628353 = 8628712

Showing the first eight; more decompositions exist.
