Solve the equation
$\left( 2+ \left( 2+ \left( 2-x \right) ^{ 2 } \right) ^{ 2 } \right) ^{ 2 } = 2020$
$x ^ { 8 } - 16 x ^ { 7 } + 120 x ^ { 6 } - 544 x ^ { 5 } + 1628 x ^ { 4 } - 3296 x ^ { 3 } + 4432 x ^ { 2 } - 3648 x + 1444 = 2020$
$\left ( \color{#FF6800}{ 2 } \color{#FF6800}{ + } \left ( \color{#FF6800}{ 2 } \color{#FF6800}{ + } \left ( \color{#FF6800}{ 2 } \color{#FF6800}{ - } \color{#FF6800}{ x } \right ) ^ { \color{#FF6800}{ 2 } } \right ) ^ { \color{#FF6800}{ 2 } } \right ) ^ { \color{#FF6800}{ 2 } } = \color{#FF6800}{ 2020 }$
