Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728348, here are decompositions:

17 + 8728331 = 8728348
59 + 8728289 = 8728348
107 + 8728241 = 8728348
137 + 8728211 = 8728348
179 + 8728169 = 8728348
269 + 8728079 = 8728348
311 + 8728037 = 8728348
359 + 8727989 = 8728348

Showing the first eight; more decompositions exist.
