Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628670, here are decompositions:

23 + 8628647 = 8628670
41 + 8628629 = 8628670
47 + 8628623 = 8628670
191 + 8628479 = 8628670
227 + 8628443 = 8628670
263 + 8628407 = 8628670
293 + 8628377 = 8628670
311 + 8628359 = 8628670

Showing the first eight; more decompositions exist.
