This number is a prime.
The largest known general prime is 47057 - 3. It was proved prime by Preda Mihailescu in March 1999 using cyclotomy primality proving.
In Mark Haddon's 2003 debut novel, The Curious Incident of the Dog
in the Night-time, Christopher John Francis Boone is an
autistic teenager who has memorized all the world's
countries and their capital cities as well as every prime
number up to 7057. [Wichmann]
