Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018150, here are decompositions:

41 + 1018109 = 1018150
53 + 1018097 = 1018150
59 + 1018091 = 1018150
131 + 1018019 = 1018150
191 + 1017959 = 1018150
197 + 1017953 = 1018150
227 + 1017923 = 1018150
269 + 1017881 = 1018150

Showing the first eight; more decompositions exist.
