Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998904, here are decompositions:

7 + 998897 = 998904
43 + 998861 = 998904
47 + 998857 = 998904
61 + 998843 = 998904
73 + 998831 = 998904
167 + 998737 = 998904
223 + 998681 = 998904
251 + 998653 = 998904

Showing the first eight; more decompositions exist.
