Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729526, here are decompositions:

59 + 8729467 = 8729526
97 + 8729429 = 8729526
137 + 8729389 = 8729526
193 + 8729333 = 8729526
199 + 8729327 = 8729526
277 + 8729249 = 8729526
283 + 8729243 = 8729526
307 + 8729219 = 8729526

Showing the first eight; more decompositions exist.
