Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729730, here are decompositions:

13 + 8729717 = 8729730
19 + 8729711 = 8729730
41 + 8729689 = 8729730
71 + 8729659 = 8729730
83 + 8729647 = 8729730
89 + 8729641 = 8729730
101 + 8729629 = 8729730
109 + 8729621 = 8729730

Showing the first eight; more decompositions exist.
