Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990250, here are decompositions:

11 + 990239 = 990250
71 + 990179 = 990250
113 + 990137 = 990250
197 + 990053 = 990250
227 + 990023 = 990250
251 + 989999 = 990250
269 + 989981 = 990250
311 + 989939 = 990250

Showing the first eight; more decompositions exist.
