Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729556, here are decompositions:

13 + 8729543 = 8729556
89 + 8729467 = 8729556
127 + 8729429 = 8729556
167 + 8729389 = 8729556
223 + 8729333 = 8729556
229 + 8729327 = 8729556
233 + 8729323 = 8729556
239 + 8729317 = 8729556

Showing the first eight; more decompositions exist.
