Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021466, here are decompositions:

3 + 1021463 = 1021466
37 + 1021429 = 1021466
79 + 1021387 = 1021466
97 + 1021369 = 1021466
139 + 1021327 = 1021466
163 + 1021303 = 1021466
223 + 1021243 = 1021466
283 + 1021183 = 1021466

Showing the first eight; more decompositions exist.
