Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622080, here are decompositions:

73 + 8622007 = 8622080
79 + 8622001 = 8622080
97 + 8621983 = 8622080
109 + 8621971 = 8622080
211 + 8621869 = 8622080
223 + 8621857 = 8622080
283 + 8621797 = 8622080
307 + 8621773 = 8622080

Showing the first eight; more decompositions exist.
