Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729508, here are decompositions:

17 + 8729491 = 8729508
41 + 8729467 = 8729508
79 + 8729429 = 8729508
97 + 8729411 = 8729508
107 + 8729401 = 8729508
181 + 8729327 = 8729508
191 + 8729317 = 8729508
199 + 8729309 = 8729508

Showing the first eight; more decompositions exist.
