Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728504, here are decompositions:

23 + 8728481 = 8728504
47 + 8728457 = 8728504
107 + 8728397 = 8728504
131 + 8728373 = 8728504
173 + 8728331 = 8728504
263 + 8728241 = 8728504
293 + 8728211 = 8728504
311 + 8728193 = 8728504

Showing the first eight; more decompositions exist.
