选尺法求解哥古猜想解答

哥德巴赫猜想与古叶猜想合成哥古猜想（Goldl]ach-Guye’s Conjecture）：任何一个非零偶数（z），都可表达为两个素数（y及x）之‘和’或‘差’；即有z＋=y＋x，或有z=y-X。当知4或五时，如何求解，及x配偶成副呢？文章介绍了求解哥古猜想解答的一种选尺法（利用‘y尺’与‘x尺’间的相对位移），它属于变尺法求解哥古猜想解答的改革措施，可使缩尺法更趋紧凑。

The Choose Rule Method in Solution of Goldbach-Guye's Conjecture

Goldbach＇s conjecture and Guye＇s conjecture compose the Goldbach-Guye＇s conjecture： any non-zero even number（z） can be expressed as the sum or subtraction of two prime （y and x）：that is z＋=y＋x,orz_=y-x.When z＋or z is known, how to solve the y and x？ This paper introduces the choose rule method （according to the slide rule principle, applying the relative displacement of fixed rule and moved rule, Goldbach-Guye ＇ s conjecture can be solved）,and puts forwards the improvement of change rule to make this method more compact.
