Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029920, here are decompositions:

13 + 1029907 = 1029920
37 + 1029883 = 1029920
61 + 1029859 = 1029920
79 + 1029841 = 1029920
97 + 1029823 = 1029920
163 + 1029757 = 1029920
223 + 1029697 = 1029920
277 + 1029643 = 1029920

Showing the first eight; more decompositions exist.
