Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021460, here are decompositions:

3 + 1021457 = 1021460
19 + 1021441 = 1021460
31 + 1021429 = 1021460
43 + 1021417 = 1021460
73 + 1021387 = 1021460
79 + 1021381 = 1021460
127 + 1021333 = 1021460
157 + 1021303 = 1021460

Showing the first eight; more decompositions exist.
