Just for perfomance boost:
sed -n '1022887{;p;q;}' /input/file
# or
awk 'NR==1022887{print;exit}' /input/file

Hope This Helps, PH.

Depending on your envrionment, you may want to test out:

head -n 1022887 /input/file | tail -n 1

PHV's sed method with quit works about twice a fast in my 8 cpu HP-UX environment.

But on my Intel-32 Centrino-M laptop with Linux the head/tail method works about on order of magnitude faster.
