Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028700, here are decompositions:

17 + 1028683 = 1028700
19 + 1028681 = 1028700
31 + 1028669 = 1028700
37 + 1028663 = 1028700
53 + 1028647 = 1028700
83 + 1028617 = 1028700
103 + 1028597 = 1028700
131 + 1028569 = 1028700

Showing the first eight; more decompositions exist.
