Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028748, here are decompositions:

11 + 1028737 = 1028748
67 + 1028681 = 1028748
79 + 1028669 = 1028748
101 + 1028647 = 1028748
131 + 1028617 = 1028748
151 + 1028597 = 1028748
167 + 1028581 = 1028748
179 + 1028569 = 1028748

Showing the first eight; more decompositions exist.
