Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729422, here are decompositions:

11 + 8729411 = 8729422
89 + 8729333 = 8729422
113 + 8729309 = 8729422
131 + 8729291 = 8729422
173 + 8729249 = 8729422
179 + 8729243 = 8729422
239 + 8729183 = 8729422
281 + 8729141 = 8729422

Showing the first eight; more decompositions exist.
