Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729258, here are decompositions:

19 + 8729239 = 8729258
37 + 8729221 = 8729258
67 + 8729191 = 8729258
79 + 8729179 = 8729258
127 + 8729131 = 8729258
151 + 8729107 = 8729258
199 + 8729059 = 8729258
271 + 8728987 = 8729258

Showing the first eight; more decompositions exist.
