Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998996, here are decompositions:

7 + 998989 = 998996
13 + 998983 = 998996
79 + 998917 = 998996
139 + 998857 = 998996
157 + 998839 = 998996
307 + 998689 = 998996
367 + 998629 = 998996
373 + 998623 = 998996

Showing the first eight; more decompositions exist.
