Numbers whose Cube equals Sum of Sequence of that many Squares/Examples

Examples of Numbers whose Cube equals Sum of Sequence of that many Squares

$47$ as Sum of Sequence of $47$ Squares

$\ds 47^3 = \sum_{k \mathop = 1}^{47} \paren {21 + k}^2$

$2161$ as Sum of Sequence of $2161$ Squares

$\ds 2161^3 = \sum_{k \mathop = 1}^{2161} \paren {988 + k}^2$

$99 \, 359$ as Sum of Sequence of $99 \, 359$ Squares

$\ds 99 \, 359^3 = \sum_{k \mathop = 1}^{99 \, 359} \paren {45 \, 449 + k}^2$
