Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645522, here are decompositions:

31 + 8645491 = 8645522
73 + 8645449 = 8645522
79 + 8645443 = 8645522
163 + 8645359 = 8645522
181 + 8645341 = 8645522
229 + 8645293 = 8645522
241 + 8645281 = 8645522
283 + 8645239 = 8645522

Showing the first eight; more decompositions exist.
