Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637256, here are decompositions:

3 + 8637253 = 8637256
29 + 8637227 = 8637256
53 + 8637203 = 8637256
137 + 8637119 = 8637256
149 + 8637107 = 8637256
197 + 8637059 = 8637256
239 + 8637017 = 8637256
269 + 8636987 = 8637256

Showing the first eight; more decompositions exist.
