Quick n dirty

$ last | grep -v "system boot" | awk '{for (i=4; i<NF; i++) printf $i " "; print $NF}'
user_193133400 
last | {m,g}awk 'gsub(/\t/, " ", $!(NF *= /system boot/))^_ * NF' \
                 FS='^[ \t]*[^ \t]*[ \t]+[^ \t]*[ \t]+[^ \t]*[ \t]+' OFS=

I only have macos ~ (BSD 4.4) and not Linux here so I can't test the output of it (even the last command looks different here). Let me know if this works or not.

If you don't care for that final gsub() bit that's more nice to have than essential, then the body is even simpler :

{m,g}awk 'NF *= /system boot/' { FS=... OFS=... }
