Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022166, here are decompositions:

29 + 1022137 = 1022166
37 + 1022129 = 1022166
43 + 1022123 = 1022166
53 + 1022113 = 1022166
83 + 1022083 = 1022166
107 + 1022059 = 1022166
113 + 1022053 = 1022166
149 + 1022017 = 1022166

Showing the first eight; more decompositions exist.
