Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729822, here are decompositions:

163 + 8729659 = 8729822
181 + 8729641 = 8729822
193 + 8729629 = 8729822
229 + 8729593 = 8729822
331 + 8729491 = 8729822
421 + 8729401 = 8729822
433 + 8729389 = 8729822
499 + 8729323 = 8729822

Showing the first eight; more decompositions exist.
