Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622160, here are decompositions:

23 + 8622137 = 8622160
47 + 8622113 = 8622160
89 + 8622071 = 8622160
137 + 8622023 = 8622160
149 + 8622011 = 8622160
227 + 8621933 = 8622160
233 + 8621927 = 8622160
263 + 8621897 = 8622160

Showing the first eight; more decompositions exist.
