Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005492, here are decompositions:

11 + 1005481 = 1005492
53 + 1005439 = 1005492
79 + 1005413 = 1005492
83 + 1005409 = 1005492
101 + 1005391 = 1005492
179 + 1005313 = 1005492
199 + 1005293 = 1005492
223 + 1005269 = 1005492

Showing the first eight; more decompositions exist.
