Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729782, here are decompositions:

53 + 8729729 = 8729782
71 + 8729711 = 8729782
101 + 8729681 = 8729782
179 + 8729603 = 8729782
239 + 8729543 = 8729782
353 + 8729429 = 8729782
449 + 8729333 = 8729782
491 + 8729291 = 8729782

Showing the first eight; more decompositions exist.
