Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990258, here are decompositions:

19 + 990239 = 990258
47 + 990211 = 990258
79 + 990179 = 990258
89 + 990169 = 990258
107 + 990151 = 990258
257 + 990001 = 990258
277 + 989981 = 990258
281 + 989977 = 990258

Showing the first eight; more decompositions exist.
