Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990474, here are decompositions:

5 + 990469 = 990474
11 + 990463 = 990474
97 + 990377 = 990474
103 + 990371 = 990474
113 + 990361 = 990474
151 + 990323 = 990474
167 + 990307 = 990474
181 + 990293 = 990474

Showing the first eight; more decompositions exist.
