Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628556, here are decompositions:

3 + 8628553 = 8628556
5 + 8628551 = 8628556
107 + 8628449 = 8628556
113 + 8628443 = 8628556
149 + 8628407 = 8628556
173 + 8628383 = 8628556
179 + 8628377 = 8628556
197 + 8628359 = 8628556

Showing the first eight; more decompositions exist.
