Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018038, here are decompositions:

17 + 1018021 = 1018038
19 + 1018019 = 1018038
31 + 1018007 = 1018038
41 + 1017997 = 1018038
79 + 1017959 = 1018038
149 + 1017889 = 1018038
157 + 1017881 = 1018038
179 + 1017859 = 1018038

Showing the first eight; more decompositions exist.
