Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021448, here are decompositions:

7 + 1021441 = 1021448
19 + 1021429 = 1021448
31 + 1021417 = 1021448
61 + 1021387 = 1021448
67 + 1021381 = 1021448
79 + 1021369 = 1021448
151 + 1021297 = 1021448
157 + 1021291 = 1021448

Showing the first eight; more decompositions exist.
