Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021424, here are decompositions:

7 + 1021417 = 1021424
37 + 1021387 = 1021424
43 + 1021381 = 1021424
97 + 1021327 = 1021424
127 + 1021297 = 1021424
163 + 1021261 = 1021424
181 + 1021243 = 1021424
241 + 1021183 = 1021424

Showing the first eight; more decompositions exist.
