Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018158, here are decompositions:

61 + 1018097 = 1018158
67 + 1018091 = 1018158
101 + 1018057 = 1018158
137 + 1018021 = 1018158
139 + 1018019 = 1018158
151 + 1018007 = 1018158
199 + 1017959 = 1018158
269 + 1017889 = 1018158

Showing the first eight; more decompositions exist.
