Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729186, here are decompositions:

3 + 8729183 = 8729186
7 + 8729179 = 8729186
13 + 8729173 = 8729186
79 + 8729107 = 8729186
127 + 8729059 = 8729186
199 + 8728987 = 8729186
223 + 8728963 = 8729186
283 + 8728903 = 8729186

Showing the first eight; more decompositions exist.
