Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018218, here are decompositions:

11 + 1018207 = 1018218
17 + 1018201 = 1018218
41 + 1018177 = 1018218
109 + 1018109 = 1018218
127 + 1018091 = 1018218
197 + 1018021 = 1018218
199 + 1018019 = 1018218
211 + 1018007 = 1018218

Showing the first eight; more decompositions exist.
