Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728056, here are decompositions:

19 + 8728037 = 8728056
67 + 8727989 = 8728056
149 + 8727907 = 8728056
157 + 8727899 = 8728056
199 + 8727857 = 8728056
277 + 8727779 = 8728056
283 + 8727773 = 8728056
367 + 8727689 = 8728056

Showing the first eight; more decompositions exist.
