Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729086, here are decompositions:

5 + 8729081 = 8729086
29 + 8729057 = 8729086
53 + 8729033 = 8729086
263 + 8728823 = 8729086
479 + 8728607 = 8729086
659 + 8728427 = 8729086
797 + 8728289 = 8729086
1013 + 8728073 = 8729086

Showing the first eight; more decompositions exist.
