Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728048, here are decompositions:

11 + 8728037 = 8728048
59 + 8727989 = 8728048
149 + 8727899 = 8728048
191 + 8727857 = 8728048
239 + 8727809 = 8728048
257 + 8727791 = 8728048
269 + 8727779 = 8728048
281 + 8727767 = 8728048

Showing the first eight; more decompositions exist.
