Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729586, here are decompositions:

23 + 8729563 = 8729586
29 + 8729557 = 8729586
43 + 8729543 = 8729586
157 + 8729429 = 8729586
197 + 8729389 = 8729586
263 + 8729323 = 8729586
269 + 8729317 = 8729586
277 + 8729309 = 8729586

Showing the first eight; more decompositions exist.
