Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022208, here are decompositions:

7 + 1022201 = 1022208
17 + 1022191 = 1022208
29 + 1022179 = 1022208
41 + 1022167 = 1022208
67 + 1022141 = 1022208
71 + 1022137 = 1022208
79 + 1022129 = 1022208
137 + 1022071 = 1022208

Showing the first eight; more decompositions exist.
