Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990488, here are decompositions:

19 + 990469 = 990488
127 + 990361 = 990488
139 + 990349 = 990488
157 + 990331 = 990488
181 + 990307 = 990488
199 + 990289 = 990488
211 + 990277 = 990488
229 + 990259 = 990488

Showing the first eight; more decompositions exist.
