As its generalization, we also establish that a positive proportion of even integers can be written as the sum of two squares of primes and two powers of 2.

作为此问题的推广，本文还建立了一个类似的数值结果：可表为两个素数的平方和两个2的方幂之和的大偶数具有正密度。

For example the square on hypotenuse of a right Angle triangle is equal to the sum of the squares of the other two sides.

例如，直角三角形斜边的平方，等于其它两边的平方和。
