Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729272, here are decompositions:

23 + 8729249 = 8729272
29 + 8729243 = 8729272
53 + 8729219 = 8729272
89 + 8729183 = 8729272
131 + 8729141 = 8729272
173 + 8729099 = 8729272
179 + 8729093 = 8729272
191 + 8729081 = 8729272

Showing the first eight; more decompositions exist.
