Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728248, here are decompositions:

7 + 8728241 = 8728248
37 + 8728211 = 8728248
41 + 8728207 = 8728248
79 + 8728169 = 8728248
101 + 8728147 = 8728248
211 + 8728037 = 8728248
311 + 8727937 = 8728248
317 + 8727931 = 8728248

Showing the first eight; more decompositions exist.
