Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729916, here are decompositions:

29 + 8729887 = 8729916
47 + 8729869 = 8729916
67 + 8729849 = 8729916
79 + 8729837 = 8729916
149 + 8729767 = 8729916
199 + 8729717 = 8729916
227 + 8729689 = 8729916
257 + 8729659 = 8729916

Showing the first eight; more decompositions exist.
