Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628456, here are decompositions:

7 + 8628449 = 8628456
13 + 8628443 = 8628456
73 + 8628383 = 8628456
79 + 8628377 = 8628456
97 + 8628359 = 8628456
103 + 8628353 = 8628456
107 + 8628349 = 8628456
163 + 8628293 = 8628456

Showing the first eight; more decompositions exist.
