Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728484, here are decompositions:

3 + 8728481 = 8728484
13 + 8728471 = 8728484
97 + 8728387 = 8728484
103 + 8728381 = 8728484
181 + 8728303 = 8728484
211 + 8728273 = 8728484
223 + 8728261 = 8728484
277 + 8728207 = 8728484

Showing the first eight; more decompositions exist.
