%N Numbers which are the sum of two perfect powers with different exponents: m = a^x + b^y with a > 0, b > 0, x > 1, y > 1 and x different from y, with m not a perfect power.
%e 2 is a term, as 2 = 1^2 + 1^3.
%e 5 is a term, as 5 = 2^2 + 1^3.
%e 17 is a term, as 17 = 1^2 + 2^4 or 3^2 + 2^3 or 4^2 + 1^3 (considering minimal possible exponents for bases equal to 1).
%Y Cf. A001597, A070049, A327609.
