Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028920, here are decompositions:

17 + 1028903 = 1028920
47 + 1028873 = 1028920
83 + 1028837 = 1028920
173 + 1028747 = 1028920
239 + 1028681 = 1028920
251 + 1028669 = 1028920
257 + 1028663 = 1028920
359 + 1028561 = 1028920

Showing the first eight; more decompositions exist.
