Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728694, here are decompositions:

3 + 8728691 = 8728694
31 + 8728663 = 8728694
67 + 8728627 = 8728694
97 + 8728597 = 8728694
103 + 8728591 = 8728694
181 + 8728513 = 8728694
211 + 8728483 = 8728694
223 + 8728471 = 8728694

Showing the first eight; more decompositions exist.
