Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021050, here are decompositions:

7 + 1021043 = 1021050
31 + 1021019 = 1021050
53 + 1020997 = 1021050
59 + 1020991 = 1021050
61 + 1020989 = 1021050
71 + 1020979 = 1021050
73 + 1020977 = 1021050
83 + 1020967 = 1021050

Showing the first eight; more decompositions exist.
