1^3+12^3=9^3+10^3
9^3+15^3=2^3+16^3
9^3+34^3=16^3+33^3
10^3+27^3=19^3+24^3
here are four given equations where a^3+b^3=c^3+d^3
where a,b,c,d are positive integers gcd(a,b,c,d) is 1 (greatest common factor)
find another equation (such that a^3+b^3<640000
obviously writing a program to do that is disallowed.
