Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042128, here are decompositions:

5 + 1042123 = 1042128
7 + 1042121 = 1042128
19 + 1042109 = 1042128
29 + 1042099 = 1042128
37 + 1042091 = 1042128
41 + 1042087 = 1042128
47 + 1042081 = 1042128
89 + 1042039 = 1042128

Showing the first eight; more decompositions exist.
