Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990498, here are decompositions:

11 + 990487 = 990498
29 + 990469 = 990498
101 + 990397 = 990498
109 + 990389 = 990498
127 + 990371 = 990498
137 + 990361 = 990498
139 + 990359 = 990498
149 + 990349 = 990498

Showing the first eight; more decompositions exist.
