Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022474, here are decompositions:

7 + 1022467 = 1022474
31 + 1022443 = 1022474
97 + 1022377 = 1022474
223 + 1022251 = 1022474
283 + 1022191 = 1022474
307 + 1022167 = 1022474
337 + 1022137 = 1022474
421 + 1022053 = 1022474

Showing the first eight; more decompositions exist.
