Is the following number Prime or Composite?

  11111 1111000100 0111111111

Can it be written as the sum of at least TWO square? And if so, what are the squares? I thank you.

11111 1111000100 0111111111 is a PRIME!.

 

It can be written as the sum of FOUR squares as follows:

n =a^2 + b^2 + c^2 + d^2

a = 962778 878031

b = 311833 920777

c = 255380 357289

d = 147337 778530
