Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728350, here are decompositions:

19 + 8728331 = 8728350
41 + 8728309 = 8728350
47 + 8728303 = 8728350
61 + 8728289 = 8728350
89 + 8728261 = 8728350
109 + 8728241 = 8728350
139 + 8728211 = 8728350
157 + 8728193 = 8728350

Showing the first eight; more decompositions exist.
