Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005384, here are decompositions:

11 + 1005373 = 1005384
13 + 1005371 = 1005384
53 + 1005331 = 1005384
67 + 1005317 = 1005384
71 + 1005313 = 1005384
97 + 1005287 = 1005384
167 + 1005217 = 1005384
181 + 1005203 = 1005384

Showing the first eight; more decompositions exist.
