Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028986, here are decompositions:

5 + 1028981 = 1028986
17 + 1028969 = 1028986
29 + 1028957 = 1028986
47 + 1028939 = 1028986
83 + 1028903 = 1028986
113 + 1028873 = 1028986
149 + 1028837 = 1028986
239 + 1028747 = 1028986

Showing the first eight; more decompositions exist.
