I have a string of this format:

words 9999 words words words 1234 words words words words 3333...

The words and numbers are unknown. Additionally, a the number of words and numbers and their order is unknown. So this is also fine:

words words words 9999 words words words words words words 1234 words 9934 4945 6945...

I want to match only the first two numbers in the string. What regex can do this?
