Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636724, here are decompositions:

11 + 8636713 = 8636724
23 + 8636701 = 8636724
53 + 8636671 = 8636724
97 + 8636627 = 8636724
137 + 8636587 = 8636724
181 + 8636543 = 8636724
191 + 8636533 = 8636724
211 + 8636513 = 8636724

Showing the first eight; more decompositions exist.
