Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729446, here are decompositions:

17 + 8729429 = 8729446
113 + 8729333 = 8729446
137 + 8729309 = 8729446
197 + 8729249 = 8729446
227 + 8729219 = 8729446
239 + 8729207 = 8729446
263 + 8729183 = 8729446
347 + 8729099 = 8729446

Showing the first eight; more decompositions exist.
