Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018200, here are decompositions:

23 + 1018177 = 1018200
103 + 1018097 = 1018200
109 + 1018091 = 1018200
179 + 1018021 = 1018200
181 + 1018019 = 1018200
193 + 1018007 = 1018200
241 + 1017959 = 1018200
277 + 1017923 = 1018200

Showing the first eight; more decompositions exist.
