I found this by watching a Numberphile video at YouTube: Every Number is the Sum of Three Palindromes - Numberphile.
www.somethingorotherwhatever.com
You'll have to go to the video (and click on the "more" under the video, and then click on the "more" in there) to access the palindrome section of the website, because I don't know exactly where it's at there, but there's a lot of other really neat stuff there.
I expect to be spending a whole lot of time there!
Ah, I finally found it!
Here it is:

So, not impressed, huh? 🤓
Guy says "AbracadabrarbadacarbA", and only that, for everything.
Really? I hadn't noticed that.
