Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021122, here are decompositions:

29 + 1021093 = 1021122
31 + 1021091 = 1021122
41 + 1021081 = 1021122
79 + 1021043 = 1021122
103 + 1021019 = 1021122
131 + 1020991 = 1021122
149 + 1020973 = 1021122
163 + 1020959 = 1021122

Showing the first eight; more decompositions exist.
