This is a very simple, easy-to-understand and easy-to-test conjecture. Even a very large-scale test based on current computer technology cannot produce a counterexample.

However, this conjecture seems simple, but it is one of the top twenty or even top ten difficult mathematical problems in the world, second only to the seven major conjectures of the millennium, and no one has been able to prove it so far.

This conjecture is even more famous in Xia Guo than the Riemann Hypothesis, ABC Conjecture, and Hodge Hypothesis, because Mr. Chen proved that "1 2", that is, any sufficiently large even number can be expressed as the sum of two numbers.

, one of which is a prime number, and the other is either a prime number or the product of two prime numbers.

This is called "Chen's theorem" by the international mathematics community, and Mr. Chen became famous all over the world and became one of the most famous mathematics masters in China and even the world.

To this day, no one can go further than Mr. Chen's "1 2".

A relatively famous research result in recent years is the "Odd Goldbach Conjecture" proved by Harald, that is, every odd number greater than 7 can be written as the sum of three odd numbers.

Qin Ke knew that the difficulty of this Goldbach's conjecture was far higher than that of the hail conjecture. With his current master-level mathematical level, it was very, very difficult to prove this Goldbach's conjecture, so he was also prepared for a protracted battle.

He was flipping through the knowledge and literature about Goldbach's conjecture in his mind, when Xiong Kaizong and Wei Wuxiang from the school basketball team came to his door.

"Brother Ke, please help us!"
