Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021108, here are decompositions:

17 + 1021091 = 1021108
41 + 1021067 = 1021108
89 + 1021019 = 1021108
107 + 1021001 = 1021108
131 + 1020977 = 1021108
149 + 1020959 = 1021108
227 + 1020881 = 1021108
269 + 1020839 = 1021108

Showing the first eight; more decompositions exist.
