Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018198, here are decompositions:

89 + 1018109 = 1018198
101 + 1018097 = 1018198
107 + 1018091 = 1018198
179 + 1018019 = 1018198
191 + 1018007 = 1018198
239 + 1017959 = 1018198
317 + 1017881 = 1018198
347 + 1017851 = 1018198

Showing the first eight; more decompositions exist.
