Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008400, here are decompositions:

47 + 1008353 = 1008400
53 + 1008347 = 1008400
83 + 1008317 = 1008400
137 + 1008263 = 1008400
167 + 1008233 = 1008400
191 + 1008209 = 1008400
269 + 1008131 = 1008400
359 + 1008041 = 1008400

Showing the first eight; more decompositions exist.
