Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628560, here are decompositions:

7 + 8628553 = 8628560
13 + 8628547 = 8628560
67 + 8628493 = 8628560
79 + 8628481 = 8628560
97 + 8628463 = 8628560
139 + 8628421 = 8628560
211 + 8628349 = 8628560
373 + 8628187 = 8628560

Showing the first eight; more decompositions exist.
