Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990408, here are decompositions:

11 + 990397 = 990408
19 + 990389 = 990408
31 + 990377 = 990408
37 + 990371 = 990408
47 + 990361 = 990408
59 + 990349 = 990408
79 + 990329 = 990408
101 + 990307 = 990408

Showing the first eight; more decompositions exist.
