Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021406, here are decompositions:

3 + 1021403 = 1021406
19 + 1021387 = 1021406
37 + 1021369 = 1021406
73 + 1021333 = 1021406
79 + 1021327 = 1021406
103 + 1021303 = 1021406
109 + 1021297 = 1021406
163 + 1021243 = 1021406

Showing the first eight; more decompositions exist.
