Not only is A6A6A6A6 not prime, but most numbers near it are also not prime (if
they would be it would be possible to use a shortcut in the algorythm to test
'near' the number, for example by incrementing or decrementing).

Our number is 2795939494. What's in it (factors to the right):

2795939494: 2 83 257 65537

Maybe this seed produced sufficiently random sequences for the OP. It would have
taken about 6 hours to run the full sequence in a 20MHz pic (IO time not
counted) so I don't think he checked it out 100%.
