Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018018, here are decompositions:

11 + 1018007 = 1018018
59 + 1017959 = 1018018
137 + 1017881 = 1018018
167 + 1017851 = 1018018
191 + 1017827 = 1018018
269 + 1017749 = 1018018
401 + 1017617 = 1018018
467 + 1017551 = 1018018

Showing the first eight; more decompositions exist.
