Spooky number for Halloween. It is a prime number. How can you prove or verify that it is prime? 1000000000000066600000000000001?

Notice two sequences of thirteen zeros with 666 in middle.

Using a computer to divide this number by every prime up to the square root of this number will take years. Is there a faster clever way to show it is prime?

    As far as I'm aware there is no special proof for Belphegor's prime, it just has to be tested by a computer program doing repeated division testing.
