Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729270, here are decompositions:

31 + 8729239 = 8729270
79 + 8729191 = 8729270
97 + 8729173 = 8729270
139 + 8729131 = 8729270
163 + 8729107 = 8729270
211 + 8729059 = 8729270
283 + 8728987 = 8729270
307 + 8728963 = 8729270

Showing the first eight; more decompositions exist.
