Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728260, here are decompositions:

19 + 8728241 = 8728260
53 + 8728207 = 8728260
67 + 8728193 = 8728260
113 + 8728147 = 8728260
131 + 8728129 = 8728260
181 + 8728079 = 8728260
223 + 8728037 = 8728260
271 + 8727989 = 8728260

Showing the first eight; more decompositions exist.
