Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018940, here are decompositions:

3 + 1018937 = 1018940
37 + 1018903 = 1018940
61 + 1018879 = 1018940
67 + 1018873 = 1018940
127 + 1018813 = 1018940
151 + 1018789 = 1018940
163 + 1018777 = 1018940
211 + 1018729 = 1018940

Showing the first eight; more decompositions exist.
