Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022216, here are decompositions:

7 + 1022209 = 1022216
37 + 1022179 = 1022216
79 + 1022137 = 1022216
103 + 1022113 = 1022216
157 + 1022059 = 1022216
163 + 1022053 = 1022216
199 + 1022017 = 1022216
337 + 1021879 = 1022216

Showing the first eight; more decompositions exist.
