Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020720, here are decompositions:

11 + 1020709 = 1020720
13 + 1020707 = 1020720
31 + 1020689 = 1020720
37 + 1020683 = 1020720
53 + 1020667 = 1020720
89 + 1020631 = 1020720
101 + 1020619 = 1020720
131 + 1020589 = 1020720

Showing the first eight; more decompositions exist.
