Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729722, here are decompositions:

5 + 8729717 = 8729722
11 + 8729711 = 8729722
41 + 8729681 = 8729722
101 + 8729621 = 8729722
179 + 8729543 = 8729722
293 + 8729429 = 8729722
311 + 8729411 = 8729722
389 + 8729333 = 8729722

Showing the first eight; more decompositions exist.
