Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028030, here are decompositions:

7 + 1028023 = 1028030
13 + 1028017 = 1028030
19 + 1028011 = 1028030
43 + 1027987 = 1028030
61 + 1027969 = 1028030
139 + 1027891 = 1028030
271 + 1027759 = 1028030
277 + 1027753 = 1028030

Showing the first eight; more decompositions exist.
