Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018008, here are decompositions:

11 + 1017997 = 1018008
127 + 1017881 = 1018008
149 + 1017859 = 1018008
151 + 1017857 = 1018008
157 + 1017851 = 1018008
181 + 1017827 = 1018008
191 + 1017817 = 1018008
227 + 1017781 = 1018008

Showing the first eight; more decompositions exist.
