The awk checks field 3 (etime) against a regular expression (RE) that checks the digits before a - character. But - I misread your first post - that's days, not hours!
Also there is a bug in the RE, should be

Code:

ps -eo pid,comm,etime | awk '$3~/^([2-9]|[0-9][0-9]+)-/{print $1,$2,$3}'

A digit in the range [2-9] or two+ digits between the start of the field and a - character.
Still this is days.
For hours, the RE would become too complicated.
So here is another one that computes the time in seconds:

Code:

ps -e -o pid= -o comm= -o etime= | awk '{n=split($3,e,"[-:]"); elapsed=e[n]+60*(e[n-1]+60*(e[n-2]+24*e[n-3]))} elapsed>7200 {print $1,$2,$3,elapsed}'

The ps is a bit longer, omits the header in a portable way.
The awk splits the field 3 into an array, delimited by the RE [-:] (a - or a : character).
Then it multiplies the array elements, so the are in seconds. Stores the sum in the variable" elapsed".
Then print if "elapsed" is greater than 7200.
It prints all three fields from the ps command, plus the "elapsed" variable. Omit what you don't need!
