Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729944, here are decompositions:

5 + 8729939 = 8729944
107 + 8729837 = 8729944
227 + 8729717 = 8729944
233 + 8729711 = 8729944
263 + 8729681 = 8729944
401 + 8729543 = 8729944
617 + 8729327 = 8729944
653 + 8729291 = 8729944

Showing the first eight; more decompositions exist.
