Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622250, here are decompositions:

41 + 8622209 = 8622250
59 + 8622191 = 8622250
113 + 8622137 = 8622250
137 + 8622113 = 8622250
179 + 8622071 = 8622250
227 + 8622023 = 8622250
233 + 8622017 = 8622250
239 + 8622011 = 8622250

Showing the first eight; more decompositions exist.
