Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005452, here are decompositions:

13 + 1005439 = 1005452
43 + 1005409 = 1005452
61 + 1005391 = 1005452
79 + 1005373 = 1005452
103 + 1005349 = 1005452
139 + 1005313 = 1005452
211 + 1005241 = 1005452
223 + 1005229 = 1005452

Showing the first eight; more decompositions exist.
