Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018138, here are decompositions:

29 + 1018109 = 1018138
41 + 1018097 = 1018138
47 + 1018091 = 1018138
131 + 1018007 = 1018138
179 + 1017959 = 1018138
257 + 1017881 = 1018138
281 + 1017857 = 1018138
311 + 1017827 = 1018138

Showing the first eight; more decompositions exist.
