Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018028, here are decompositions:

7 + 1018021 = 1018028
31 + 1017997 = 1018028
139 + 1017889 = 1018028
181 + 1017847 = 1018028
211 + 1017817 = 1018028
229 + 1017799 = 1018028
241 + 1017787 = 1018028
307 + 1017721 = 1018028

Showing the first eight; more decompositions exist.
