Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728704, here are decompositions:

13 + 8728691 = 8728704
41 + 8728663 = 8728704
97 + 8728607 = 8728704
107 + 8728597 = 8728704
113 + 8728591 = 8728704
191 + 8728513 = 8728704
223 + 8728481 = 8728704
233 + 8728471 = 8728704

Showing the first eight; more decompositions exist.
