Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729550, here are decompositions:

7 + 8729543 = 8729550
59 + 8729491 = 8729550
83 + 8729467 = 8729550
139 + 8729411 = 8729550
149 + 8729401 = 8729550
223 + 8729327 = 8729550
227 + 8729323 = 8729550
233 + 8729317 = 8729550

Showing the first eight; more decompositions exist.
