Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005728, here are decompositions:

19 + 1005709 = 1005728
67 + 1005661 = 1005728
109 + 1005619 = 1005728
271 + 1005457 = 1005728
337 + 1005391 = 1005728
379 + 1005349 = 1005728
397 + 1005331 = 1005728
487 + 1005241 = 1005728

Showing the first eight; more decompositions exist.
