Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028760, here are decompositions:

11 + 1028749 = 1028760
13 + 1028747 = 1028760
23 + 1028737 = 1028760
79 + 1028681 = 1028760
97 + 1028663 = 1028760
113 + 1028647 = 1028760
163 + 1028597 = 1028760
179 + 1028581 = 1028760

Showing the first eight; more decompositions exist.
