Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729470, here are decompositions:

3 + 8729467 = 8729470
41 + 8729429 = 8729470
59 + 8729411 = 8729470
137 + 8729333 = 8729470
179 + 8729291 = 8729470
227 + 8729243 = 8729470
251 + 8729219 = 8729470
263 + 8729207 = 8729470

Showing the first eight; more decompositions exist.
