Including the @Kobi's suggestion.

I believe ^\d{2}(\s\d{2})+$ should fit your needs.

What you need are word boundaries, try

\b\d{2}\b

See it here on Regexr.

\b matches a wordboundary (in a lot of languages), thats the change from a wordcharacter to a non wordcharacter. Means, the regex would match 2 digits, if there is no digit or letter before and ahead.

\d works in most regex flavours as a shortcut for [0-9], some does not support this shortcut and some use the Unicode version and match any kind of number with \d
