Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025128, here are decompositions:

17 + 1025111 = 1025128
29 + 1025099 = 1025128
47 + 1025081 = 1025128
89 + 1025039 = 1025128
107 + 1025021 = 1025128
131 + 1024997 = 1025128
197 + 1024931 = 1025128
227 + 1024901 = 1025128

Showing the first eight; more decompositions exist.
