Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728452, here are decompositions:

71 + 8728381 = 8728452
79 + 8728373 = 8728452
149 + 8728303 = 8728452
163 + 8728289 = 8728452
179 + 8728273 = 8728452
191 + 8728261 = 8728452
211 + 8728241 = 8728452
241 + 8728211 = 8728452

Showing the first eight; more decompositions exist.
