Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020816, here are decompositions:

19 + 1020797 = 1020816
37 + 1020779 = 1020816
59 + 1020757 = 1020816
73 + 1020743 = 1020816
107 + 1020709 = 1020816
109 + 1020707 = 1020816
127 + 1020689 = 1020816
149 + 1020667 = 1020816

Showing the first eight; more decompositions exist.
