i have tried it for 15 minutes,
Timing[PrimeQ[33759183*2^123459-1]]
and when my cpu begins to heat more than 50 Cel. degree i stopped the program, because i have a previous experience of another pc damaged from heating the cpu. and the 50 degree indeed more than that, and my pc begins to slow down. someone may said 50 C. degree is normal, but this heating is specific to every pc alone, when i got 50 or more i have problems. also this heating does not refer to the ram memory which can be heated to the damaging point since there is no Fan over the ram memory.
if you zipped or rared the txt file it may be uploaded, try it as an experiment.
the curent modern i7-... cpu's are more efficient.
that number discovered in 2009, they may used universities super computers.
