Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628256, here are decompositions:

23 + 8628233 = 8628256
53 + 8628203 = 8628256
83 + 8628173 = 8628256
107 + 8628149 = 8628256
149 + 8628107 = 8628256
179 + 8628077 = 8628256
239 + 8628017 = 8628256
269 + 8627987 = 8628256

Showing the first eight; more decompositions exist.
