Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1058820, here are decompositions:

11 + 1058809 = 1058820
13 + 1058807 = 1058820
17 + 1058803 = 1058820
29 + 1058791 = 1058820
41 + 1058779 = 1058820
47 + 1058773 = 1058820
53 + 1058767 = 1058820
67 + 1058753 = 1058820

Showing the first eight; more decompositions exist.
