Just make the \w match non-greedy. The last test case below is
questionable, but the OP didn't specify what to do in that case.
There's also the "match against the reversed string and reverse the
matches" approach :)

for ("suite 111", "suite222", " 111", "222")
{
if (/^(\w+?)\s*(\d+)$/) # match \w characters conservatively
{
print "$_: $1 - $2\n";
}
else
{
print "$_: no match\n";
}
}
-->
suite 111: suite - 111
suite222: suite - 222
111: no match
222: 2 - 22
