Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005140, here are decompositions:

7 + 1005133 = 1005140
61 + 1005079 = 1005140
67 + 1005073 = 1005140
127 + 1005013 = 1005140
163 + 1004977 = 1005140
223 + 1004917 = 1005140
229 + 1004911 = 1005140
379 + 1004761 = 1005140

Showing the first eight; more decompositions exist.
