Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020790, here are decompositions:

11 + 1020779 = 1020790
47 + 1020743 = 1020790
83 + 1020707 = 1020790
101 + 1020689 = 1020790
107 + 1020683 = 1020790
191 + 1020599 = 1020790
233 + 1020557 = 1020790
359 + 1020431 = 1020790

Showing the first eight; more decompositions exist.
