Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022406, here are decompositions:

17 + 1022389 = 1022406
19 + 1022387 = 1022406
23 + 1022383 = 1022406
29 + 1022377 = 1022406
103 + 1022303 = 1022406
157 + 1022249 = 1022406
163 + 1022243 = 1022406
197 + 1022209 = 1022406

Showing the first eight; more decompositions exist.
