Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729566, here are decompositions:

3 + 8729563 = 8729566
23 + 8729543 = 8729566
137 + 8729429 = 8729566
233 + 8729333 = 8729566
239 + 8729327 = 8729566
257 + 8729309 = 8729566
317 + 8729249 = 8729566
347 + 8729219 = 8729566

Showing the first eight; more decompositions exist.
