Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005404, here are decompositions:

13 + 1005391 = 1005404
31 + 1005373 = 1005404
73 + 1005331 = 1005404
163 + 1005241 = 1005404
181 + 1005223 = 1005404
271 + 1005133 = 1005404
331 + 1005073 = 1005404
397 + 1005007 = 1005404

Showing the first eight; more decompositions exist.
