Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729320, here are decompositions:

3 + 8729317 = 8729320
11 + 8729309 = 8729320
29 + 8729291 = 8729320
71 + 8729249 = 8729320
101 + 8729219 = 8729320
113 + 8729207 = 8729320
137 + 8729183 = 8729320
179 + 8729141 = 8729320

Showing the first eight; more decompositions exist.
