Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622288, here are decompositions:

47 + 8622241 = 8622288
79 + 8622209 = 8622288
97 + 8622191 = 8622288
151 + 8622137 = 8622288
271 + 8622017 = 8622288
277 + 8622011 = 8622288
281 + 8622007 = 8622288
317 + 8621971 = 8622288

Showing the first eight; more decompositions exist.
