Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990384, here are decompositions:

7 + 990377 = 990384
13 + 990371 = 990384
23 + 990361 = 990384
53 + 990331 = 990384
61 + 990323 = 990384
71 + 990313 = 990384
97 + 990287 = 990384
103 + 990281 = 990384

Showing the first eight; more decompositions exist.
