Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729832, here are decompositions:

11 + 8729821 = 8729832
31 + 8729801 = 8729832
103 + 8729729 = 8729832
151 + 8729681 = 8729832
173 + 8729659 = 8729832
191 + 8729641 = 8729832
211 + 8729621 = 8729832
229 + 8729603 = 8729832

Showing the first eight; more decompositions exist.
