Is this number Prime or Composite? And how do you determine it?

(((((2^3+3)^3+30)^3+6)^3+80)^3+12. Thanks for help.

(((((2^3+3)^3+30)^3+6)^3+80)^3+12

=4113101149215104800030529537915953170486139623539759933135949994882770404074832568499(85 digits)

This is the 6th Prime Number in a series of primes called "Mills Primes" after the mathematician William Mills(1947). This is of the form: [A^3^n], A being Mills constant and n any whole integer,1, 2, 3....etc.
