Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005512, here are decompositions:

19 + 1005493 = 1005512
31 + 1005481 = 1005512
73 + 1005439 = 1005512
103 + 1005409 = 1005512
139 + 1005373 = 1005512
163 + 1005349 = 1005512
181 + 1005331 = 1005512
199 + 1005313 = 1005512

Showing the first eight; more decompositions exist.
