use long long int instead of int for X and all except t.and type cast the
sqrt returned value to integer..like int(sqrt(X))

Hi Saurabh,
Can you try it for 10? Could not really understand, what are you gonna
communicate?
10 = 2*5 (2^2 + 1^2 )*(1*2 + 1^2)... If with this logic you are saying 10 is
prime then all numbers divisible by 5 should be prime.
Could you elaborate your answer more?
Thanks & Regards

In fact we can...though not directly..SInce every number can be broken down
as facotrs of primeUse that property

For more options,
@ashish you forget one condition that c=x^2+y^2 iff c= 1 mod(4) e.g. c
%4==1 & also x!=y see above link its great & simple.
Thanks to Fermat & Euler
