Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728254, here are decompositions:

13 + 8728241 = 8728254
43 + 8728211 = 8728254
47 + 8728207 = 8728254
61 + 8728193 = 8728254
107 + 8728147 = 8728254
181 + 8728073 = 8728254
317 + 8727937 = 8728254
347 + 8727907 = 8728254

Showing the first eight; more decompositions exist.
