Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729724, here are decompositions:

7 + 8729717 = 8729724
13 + 8729711 = 8729724
43 + 8729681 = 8729724
83 + 8729641 = 8729724
103 + 8729621 = 8729724
131 + 8729593 = 8729724
167 + 8729557 = 8729724
181 + 8729543 = 8729724

Showing the first eight; more decompositions exist.
