Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021066, here are decompositions:

23 + 1021043 = 1021066
47 + 1021019 = 1021066
89 + 1020977 = 1021066
107 + 1020959 = 1021066
173 + 1020893 = 1021066
227 + 1020839 = 1021066
239 + 1020827 = 1021066
269 + 1020797 = 1021066

Showing the first eight; more decompositions exist.
