Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021328, here are decompositions:

31 + 1021297 = 1021328
37 + 1021291 = 1021328
67 + 1021261 = 1021328
199 + 1021129 = 1021328
241 + 1021087 = 1021328
331 + 1020997 = 1021328
337 + 1020991 = 1021328
349 + 1020979 = 1021328

Showing the first eight; more decompositions exist.
