Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622340, here are decompositions:

3 + 8622337 = 8622340
17 + 8622323 = 8622340
47 + 8622293 = 8622340
53 + 8622287 = 8622340
131 + 8622209 = 8622340
149 + 8622191 = 8622340
227 + 8622113 = 8622340
269 + 8622071 = 8622340

Showing the first eight; more decompositions exist.
