Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020978, here are decompositions:

5 + 1020973 = 1020978
11 + 1020967 = 1020978
17 + 1020961 = 1020978
19 + 1020959 = 1020978
47 + 1020931 = 1020978
71 + 1020907 = 1020978
97 + 1020881 = 1020978
131 + 1020847 = 1020978

Showing the first eight; more decompositions exist.
