script to get a string after regex and replace it on each line with a match

So far have been able to extract the sting between the pattern match but havent been able to extend it to print as required.

My file content:

my number 12345 string1 string2
my number 789 string1 string2
my number 456789023 string3 string4

Next command

sed -e "s/.*number//;s/string.*//" filename

gives me output

 12345 
 789 
 456789023

I need help to extend it or a better way to print output

my number 12345 num 12345 string1 string2
my number 789 num 789 string1 string2
my number 456789023 num 456789023 string3 string4

This might work for you:

sed 's/[0-9]\+/& num &/' file

From your example, I derive:

sed -r "s/number (.*) string/number \1 num \1 string/" FILE
