Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018108, here are decompositions:

11 + 1018097 = 1018108
17 + 1018091 = 1018108
89 + 1018019 = 1018108
101 + 1018007 = 1018108
149 + 1017959 = 1018108
227 + 1017881 = 1018108
251 + 1017857 = 1018108
257 + 1017851 = 1018108

Showing the first eight; more decompositions exist.
