Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990198, here are decompositions:

17 + 990181 = 990198
19 + 990179 = 990198
29 + 990169 = 990198
47 + 990151 = 990198
61 + 990137 = 990198
197 + 990001 = 990198
199 + 989999 = 990198
227 + 989971 = 990198

Showing the first eight; more decompositions exist.
