Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999006, here are decompositions:

17 + 998989 = 999006
23 + 998983 = 999006
37 + 998969 = 999006
59 + 998947 = 999006
79 + 998927 = 999006
89 + 998917 = 999006
97 + 998909 = 999006
109 + 998897 = 999006

Showing the first eight; more decompositions exist.
