Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728258, here are decompositions:

17 + 8728241 = 8728258
47 + 8728211 = 8728258
89 + 8728169 = 8728258
179 + 8728079 = 8728258
269 + 8727989 = 8728258
359 + 8727899 = 8728258
401 + 8727857 = 8728258
449 + 8727809 = 8728258

Showing the first eight; more decompositions exist.
