Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020810, here are decompositions:

13 + 1020797 = 1020810
31 + 1020779 = 1020810
53 + 1020757 = 1020810
59 + 1020751 = 1020810
67 + 1020743 = 1020810
101 + 1020709 = 1020810
103 + 1020707 = 1020810
127 + 1020683 = 1020810

Showing the first eight; more decompositions exist.
