Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021004, here are decompositions:

3 + 1021001 = 1021004
7 + 1020997 = 1021004
13 + 1020991 = 1021004
31 + 1020973 = 1021004
37 + 1020967 = 1021004
43 + 1020961 = 1021004
73 + 1020931 = 1021004
97 + 1020907 = 1021004

Showing the first eight; more decompositions exist.
