Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990254, here are decompositions:

43 + 990211 = 990254
73 + 990181 = 990254
103 + 990151 = 990254
211 + 990043 = 990254
241 + 990013 = 990254
277 + 989977 = 990254
283 + 989971 = 990254
337 + 989917 = 990254

Showing the first eight; more decompositions exist.
