Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728068, here are decompositions:

31 + 8728037 = 8728068
79 + 8727989 = 8728068
131 + 8727937 = 8728068
137 + 8727931 = 8728068
197 + 8727871 = 8728068
211 + 8727857 = 8728068
277 + 8727791 = 8728068
311 + 8727757 = 8728068

Showing the first eight; more decompositions exist.
