It turns out that the "prime" 455*2^1560160-1 that Sashixi found was not prime.

After not being able to get a hold of him, I submitted it to the top-5000 site and it came back as composite. In the future, I will doublecheck any prime that this user finds.

Dave, can you remove this "prime" from the database? Thanks.
