Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622210, here are decompositions:

19 + 8622191 = 8622210
73 + 8622137 = 8622210
83 + 8622127 = 8622210
97 + 8622113 = 8622210
139 + 8622071 = 8622210
193 + 8622017 = 8622210
199 + 8622011 = 8622210
227 + 8621983 = 8622210

Showing the first eight; more decompositions exist.
