Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729826, here are decompositions:

5 + 8729821 = 8729826
59 + 8729767 = 8729826
97 + 8729729 = 8729826
109 + 8729717 = 8729826
137 + 8729689 = 8729826
167 + 8729659 = 8729826
179 + 8729647 = 8729826
197 + 8729629 = 8729826

Showing the first eight; more decompositions exist.
