Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1065140, here are decompositions:

3 + 1065137 = 1065140
7 + 1065133 = 1065140
31 + 1065109 = 1065140
67 + 1065073 = 1065140
103 + 1065037 = 1065140
127 + 1065013 = 1065140
151 + 1064989 = 1065140
163 + 1064977 = 1065140

Showing the first eight; more decompositions exist.
