Is the question undeleted? Challenge
Given a positive integer, determine whether that number is currently being used to represent a question on PPCG.
The question must not have been removed, but may be open or closed.
The number is the one being used in the URL of the question, such as:

https://codegolf.stackexchange.com/questions/[input]

Note that this questions is tagged stack-exchange-api, but you may not need this to complete the challenge.

Examples

1: Truthy (represents Just Another Perl Hacker)
3: Falsey (was once Solve the Tower of Hanoi, but was removed by a moderator.
127030: Falsey (was once Helping Danny to Maximize his Score, but was removed by the author.)
127147: Truthy (Fastest algorithm to take the product of all subsets)


Scoring
This is code-golf, so the shortest answer in each language wins.
bash, 52 bytes

curl -IL codegolf.stackexchange.com/q/$1|grep 2\ 200


Takes input as a command line argument, and outputs in the form of exit code: 0 or "success" (truthy) for an undeleted question, and 1 or "failure" (falsy) for a nonexistent or deleted question.

It also prints a bunch of junk to STDERR and potentially STDOUT, but this is allowed to be ignored as per meta.

As an explanation, the -I flag to curl sends an HTTP HEAD request (fetch only the headers), and -L will follow redirects (http to https, and then /q to /questions). The full output from the curl command will look something like this:

Note that the 2\ 200 (equivalent to '2 200') will match the line HTTP/2 200 if it exists (HTTP OK), and it will not match HTTP/2 404 (Not Found) for questions that do not exist. (The inclusion of the 2 is necessary to avoid false positives if some of the other headers happen to contain the sequence 200.)
