Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021006, here are decompositions:

5 + 1021001 = 1021006
17 + 1020989 = 1021006
29 + 1020977 = 1021006
47 + 1020959 = 1021006
113 + 1020893 = 1021006
167 + 1020839 = 1021006
179 + 1020827 = 1021006
227 + 1020779 = 1021006

Showing the first eight; more decompositions exist.
