Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729800, here are decompositions:

71 + 8729729 = 8729800
83 + 8729717 = 8729800
89 + 8729711 = 8729800
179 + 8729621 = 8729800
197 + 8729603 = 8729800
257 + 8729543 = 8729800
389 + 8729411 = 8729800
467 + 8729333 = 8729800

Showing the first eight; more decompositions exist.
