Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021584, here are decompositions:

7 + 1021577 = 1021584
13 + 1021571 = 1021584
23 + 1021561 = 1021584
43 + 1021541 = 1021584
97 + 1021487 = 1021584
101 + 1021483 = 1021584
127 + 1021457 = 1021584
167 + 1021417 = 1021584

Showing the first eight; more decompositions exist.
