Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017158, here are decompositions:

19 + 1017139 = 1017158
61 + 1017097 = 1017158
97 + 1017061 = 1017158
127 + 1017031 = 1017158
151 + 1017007 = 1017158
199 + 1016959 = 1017158
211 + 1016947 = 1017158
229 + 1016929 = 1017158

Showing the first eight; more decompositions exist.
