Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8652640, here are decompositions:

11 + 8652629 = 8652640
47 + 8652593 = 8652640
53 + 8652587 = 8652640
89 + 8652551 = 8652640
179 + 8652461 = 8652640
233 + 8652407 = 8652640
239 + 8652401 = 8652640
251 + 8652389 = 8652640

Showing the first eight; more decompositions exist.
