Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040128, here are decompositions:

59 + 1040069 = 1040128
71 + 1040057 = 1040128
107 + 1040021 = 1040128
149 + 1039979 = 1040128
179 + 1039949 = 1040128
197 + 1039931 = 1040128
227 + 1039901 = 1040128
311 + 1039817 = 1040128

Showing the first eight; more decompositions exist.
