Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729198, here are decompositions:

7 + 8729191 = 8729198
19 + 8729179 = 8729198
67 + 8729131 = 8729198
139 + 8729059 = 8729198
211 + 8728987 = 8729198
229 + 8728969 = 8729198
271 + 8728927 = 8729198
277 + 8728921 = 8729198

Showing the first eight; more decompositions exist.
