Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728552, here are decompositions:

3 + 8728549 = 8728552
71 + 8728481 = 8728552
179 + 8728373 = 8728552
263 + 8728289 = 8728552
311 + 8728241 = 8728552
359 + 8728193 = 8728552
383 + 8728169 = 8728552
479 + 8728073 = 8728552

Showing the first eight; more decompositions exist.
