Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018122, here are decompositions:

13 + 1018109 = 1018122
31 + 1018091 = 1018122
101 + 1018021 = 1018122
103 + 1018019 = 1018122
163 + 1017959 = 1018122
199 + 1017923 = 1018122
233 + 1017889 = 1018122
241 + 1017881 = 1018122

Showing the first eight; more decompositions exist.
