Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990008, here are decompositions:

7 + 990001 = 990008
31 + 989977 = 990008
37 + 989971 = 990008
79 + 989929 = 990008
139 + 989869 = 990008
181 + 989827 = 990008
211 + 989797 = 990008
337 + 989671 = 990008

Showing the first eight; more decompositions exist.
