Miracles happen from time to time... and I discovered the second Fermat factor of this year, my very first on my birthday's week!
I started searching with Leonid Durman in the late 1990.
The factor has 30 digits, and was found using a Intel 9800x with a Nvidia RTX2060 and the program mmff from George Woltman.
Congratulations to FermatSearch, we now have 357 Fermat factors known!

Congratulations Luigi! And a Happy Birthday (best Birthday present ever!)
