Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728874, here are decompositions:

67 + 8728807 = 8728874
157 + 8728717 = 8728874
163 + 8728711 = 8728874
211 + 8728663 = 8728874
277 + 8728597 = 8728874
283 + 8728591 = 8728874
487 + 8728387 = 8728874
571 + 8728303 = 8728874

Showing the first eight; more decompositions exist.
