Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999008, here are decompositions:

19 + 998989 = 999008
61 + 998947 = 999008
67 + 998941 = 999008
151 + 998857 = 999008
229 + 998779 = 999008
271 + 998737 = 999008
379 + 998629 = 999008
457 + 998551 = 999008

Showing the first eight; more decompositions exist.
