Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728296, here are decompositions:

7 + 8728289 = 8728296
23 + 8728273 = 8728296
89 + 8728207 = 8728296
103 + 8728193 = 8728296
127 + 8728169 = 8728296
149 + 8728147 = 8728296
167 + 8728129 = 8728296
223 + 8728073 = 8728296

Showing the first eight; more decompositions exist.
