%N Numbers that are the sum of a cube s and a square t such that 0 < s < t.

%e 17 is in the sequence since 1^3 + 4^2 = 1 + 16 = 17, where 0 < 1 < 16.

%t Table[If[Sum[(Floor[i^(1/3)] - Floor[(i - 1)^(1/3)]) (Floor[(n - i)^(1/2)] - Floor[(n - i - 1)^(1/2)]), {i, Floor[(n - 1)/2]}] > 0, n, {}], {n, 500}] // Flatten
