Unfortunately it's not a prime :

Code:
2855451057157704997579326497626590663028969 =
896774094182730749591 * 3184136423744490284159
So you found two factors in time. You can check this for example with a UBASIC program like ECMX.
A list with p-1 records you can find in the ECMnet pages : http://www.loria.fr/~zimmerma/records/Pminus1.html
