Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005200, here are decompositions:

13 + 1005187 = 1005200
67 + 1005133 = 1005200
127 + 1005073 = 1005200
151 + 1005049 = 1005200
181 + 1005019 = 1005200
193 + 1005007 = 1005200
223 + 1004977 = 1005200
283 + 1004917 = 1005200

Showing the first eight; more decompositions exist.
