Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163998, here are decompositions:

5 + 163993 = 163998
7 + 163991 = 163998
11 + 163987 = 163998
17 + 163981 = 163998
19 + 163979 = 163998
71 + 163927 = 163998
89 + 163909 = 163998
97 + 163901 = 163998

Showing the first eight; more decompositions exist.
