Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728510, here are decompositions:

29 + 8728481 = 8728510
53 + 8728457 = 8728510
83 + 8728427 = 8728510
113 + 8728397 = 8728510
137 + 8728373 = 8728510
179 + 8728331 = 8728510
269 + 8728241 = 8728510
317 + 8728193 = 8728510

Showing the first eight; more decompositions exist.
