Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729104, here are decompositions:

5 + 8729099 = 8729104
11 + 8729093 = 8729104
23 + 8729081 = 8729104
47 + 8729057 = 8729104
53 + 8729051 = 8729104
71 + 8729033 = 8729104
281 + 8728823 = 8729104
317 + 8728787 = 8729104

Showing the first eight; more decompositions exist.
