Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622146, here are decompositions:

19 + 8622127 = 8622146
139 + 8622007 = 8622146
157 + 8621989 = 8622146
163 + 8621983 = 8622146
199 + 8621947 = 8622146
277 + 8621869 = 8622146
283 + 8621863 = 8622146
349 + 8621797 = 8622146

Showing the first eight; more decompositions exist.
