Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028158, here are decompositions:

17 + 1028141 = 1028158
29 + 1028129 = 1028158
41 + 1028117 = 1028158
59 + 1028099 = 1028158
107 + 1028051 = 1028158
227 + 1027931 = 1028158
317 + 1027841 = 1028158
359 + 1027799 = 1028158

Showing the first eight; more decompositions exist.
