Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018194, here are decompositions:

17 + 1018177 = 1018194
71 + 1018123 = 1018194
97 + 1018097 = 1018194
103 + 1018091 = 1018194
137 + 1018057 = 1018194
173 + 1018021 = 1018194
197 + 1017997 = 1018194
241 + 1017953 = 1018194

Showing the first eight; more decompositions exist.
