Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020992, here are decompositions:

3 + 1020989 = 1020992
13 + 1020979 = 1020992
19 + 1020973 = 1020992
31 + 1020961 = 1020992
61 + 1020931 = 1020992
79 + 1020913 = 1020992
139 + 1020853 = 1020992
151 + 1020841 = 1020992

Showing the first eight; more decompositions exist.
