Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026816, here are decompositions:

5 + 1026811 = 1026816
17 + 1026799 = 1026816
59 + 1026757 = 1026816
83 + 1026733 = 1026816
107 + 1026709 = 1026816
137 + 1026679 = 1026816
139 + 1026677 = 1026816
149 + 1026667 = 1026816

Showing the first eight; more decompositions exist.
