Question 51

Perfect pair - we say that 2 natural numbers form a perfect pair when the sum and product of these two numbers are perfect squares. For example, $5$ and $20$ form a perfect pair, since $5+20=25=5^{2}$ and $5 \times 20=100=10^{2}$. Does $122$ form a perfect pair with another natural one?
