Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729418, here are decompositions:

7 + 8729411 = 8729418
17 + 8729401 = 8729418
29 + 8729389 = 8729418
101 + 8729317 = 8729418
109 + 8729309 = 8729418
127 + 8729291 = 8729418
179 + 8729239 = 8729418
197 + 8729221 = 8729418

Showing the first eight; more decompositions exist.
