Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990884, here are decompositions:

3 + 990881 = 990884
43 + 990841 = 990884
151 + 990733 = 990884
211 + 990673 = 990884
241 + 990643 = 990884
337 + 990547 = 990884
373 + 990511 = 990884
397 + 990487 = 990884

Showing the first eight; more decompositions exist.
