Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729328, here are decompositions:

5 + 8729323 = 8729328
11 + 8729317 = 8729328
19 + 8729309 = 8729328
37 + 8729291 = 8729328
79 + 8729249 = 8729328
89 + 8729239 = 8729328
107 + 8729221 = 8729328
109 + 8729219 = 8729328

Showing the first eight; more decompositions exist.
