Default 3^10000+2 is composite

Testing my integer calculator, I tried factoring 3^10000+2,
a 4772 digit integer of previously unknown status.
No small ( <= 2099963) factors found.
Then the PRP tester kicked in.
Eventually (not too long), it reported COMPOSITE.

I checked with factordb.
Its smallest prmie factor is 8099873.
