你的任務就是寫一個程式輸出對每一個大於4的偶數，可以找到幾組這樣的奇數質數的組合。請注意：我們只對有幾組不同的組合有興趣，所以(p1,p2)和(p2,p1)不應該被視為不同的組合。

This conjecture has not been proved nor refused yet. No one is sure whether this conjecture actually holds. However, one can find such a pair of prime numbers, if any, for a given even number. The problem here is to write a program that reports the number of all the pairs of prime numbers satisfying the condition in the conjecture for a given even number.

Uva原題及原猜想皆並未要求兩者皆為奇數
