Lightbulb Tune my query

I have a requirement to separate only some numbers from the input file and produce it in a format.
The input is ( i have took a sample, the actual file contains more than 50000 rows around 840 MB in size)
$cat temp.txt
001 08  002 08  003 06  004 11  005 11  006 08
007 08  008 92* 009 92  010 92  011 92  012 92
013 92  014 92  015 92  016 92  017 92* 018 92

I use the script like below
awk '{for(i=1;i<=NF;i=i+2) {x =i+1; print $i,$x ; print "\n";}}' temp.txt | awk '/*/ {print "substr($2,1,2), $1}'
The output is
92 008 
92 017

Could you please tune my script which will have only one awk or some other commands. Appriciate your help on this.

Try this one:

awk '{for(i=2;i<NF;i+=2){if($i ~ /\*/){print int($i), $(i-1)}}}' file
