Yes
2^50 + 1 = prime number.
why???
Because when the exponent is even, while the base is 2, the result is always 1 digit less than prime number
how.....
(2^0) + 1 = 2...........prime
(2^2) + 1 = 5...........prime
(2^4) + 1 = 17.........prime
(2^6) + 1 = 65.........prime
(2^8) + 1 =257........prime
(2^10) + 1 = 1025...prime
Therefore if n is even, then
(2^n) + 1 = always prime
