That is incorrect, it was factored on January 21, 2023, after the guess was made.
Happy Lunar New Year of the Water Rabbit!

I believe I have 2 unused guesses:

Uncwilly	9/29/2021	111999799	5/27/2022

So, my new guesses will be:
113998301 on April 15, 2023
117003127 on December 24, 2023
121596571 on May 4, 2024

Uncwilly	1/19/2023	117003127	12/24/2023
masser  	12/12/2018	117003179	11/24/2022

Don't stand so close to me. I believe my 60 days have passed, so I will make a new prediction.

You have 1 available.
Kvasir posted on 12/9/2021 a guess of 110235199 with a date of 12/2/2022
12/2/2022 is not yet 60 days in the past.

A further problem is 99350453 has been tested and verified as composite. Any exponent with matching LL's or a PRP that has been verified are proven composite and thus not a suitable guess. Thus a 60 day wait from the time of your posting is invoked according to the rules.

I see Kriesel is checking the number 198180559 and he will do a PRP test. This is really cool thanks it helps me a lot (I'm currently checking another number)

Can I predict a number than I'm checking (I mean assigned) ? I have still 2 available If I understand

Just note rule #8

The discoverer of M52 (not the 'noticer') will have all guesses posted more than 10 hours after they were assigned and/or started the expo (whichever is first) that is reported to be prime hereby disqualified.
