Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665522, here are decompositions:

23 + 8665499 = 8665522
53 + 8665469 = 8665522
71 + 8665451 = 8665522
113 + 8665409 = 8665522
149 + 8665373 = 8665522
263 + 8665259 = 8665522
269 + 8665253 = 8665522
449 + 8665073 = 8665522

Showing the first eight; more decompositions exist.
