Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990266, here are decompositions:

7 + 990259 = 990266
97 + 990169 = 990266
103 + 990163 = 990266
223 + 990043 = 990266
229 + 990037 = 990266
307 + 989959 = 990266
337 + 989929 = 990266
349 + 989917 = 990266

Showing the first eight; more decompositions exist.
