Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628474, here are decompositions:

11 + 8628463 = 8628474
31 + 8628443 = 8628474
53 + 8628421 = 8628474
67 + 8628407 = 8628474
97 + 8628377 = 8628474
181 + 8628293 = 8628474
241 + 8628233 = 8628474
271 + 8628203 = 8628474

Showing the first eight; more decompositions exist.
