Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987996, here are decompositions:

5 + 987991 = 987996
13 + 987983 = 987996
17 + 987979 = 987996
67 + 987929 = 987996
83 + 987913 = 987996
127 + 987869 = 987996
193 + 987803 = 987996
199 + 987797 = 987996

Showing the first eight; more decompositions exist.
