Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005446, here are decompositions:

7 + 1005439 = 1005446
19 + 1005427 = 1005446
37 + 1005409 = 1005446
73 + 1005373 = 1005446
97 + 1005349 = 1005446
223 + 1005223 = 1005446
229 + 1005217 = 1005446
313 + 1005133 = 1005446

Showing the first eight; more decompositions exist.
