Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728998, here are decompositions:

11 + 8728987 = 8728998
29 + 8728969 = 8728998
71 + 8728927 = 8728998
97 + 8728901 = 8728998
101 + 8728897 = 8728998
149 + 8728849 = 8728998
191 + 8728807 = 8728998
211 + 8728787 = 8728998

Showing the first eight; more decompositions exist.
