Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005260, here are decompositions:

19 + 1005241 = 1005260
31 + 1005229 = 1005260
37 + 1005223 = 1005260
43 + 1005217 = 1005260
73 + 1005187 = 1005260
127 + 1005133 = 1005260
181 + 1005079 = 1005260
211 + 1005049 = 1005260

Showing the first eight; more decompositions exist.
