Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990270, here are decompositions:

11 + 990259 = 990270
31 + 990239 = 990270
59 + 990211 = 990270
89 + 990181 = 990270
101 + 990169 = 990270
107 + 990163 = 990270
227 + 990043 = 990270
233 + 990037 = 990270

Showing the first eight; more decompositions exist.
