This week’s problem gives you a chance to become famous (and potentially rich)!  German mathematician Christian Goldbach (above) in 1742 proposed the following conjecture:

“Every even integer greater than 2 can be written as the sum of 2 prime numbers.”

Over 250 years later no-one has been able to prove it.  Anyone who can prove it get $1 million and would enter the mathematical history books!  Can you find make a start by finding all the solutions to following?

You can download a pdf of the solution here.

Teacher notes:

Level of difficulty:  Accessible for all students

Syllabus knowledge required:  None.

This would be a good starter to support a lesson on proof

I am Head of Mathematics at a leading international school in Thailand. I am also a current IB examiner for the IB Mathematics coursework with an MSc. in Mathematics. Some of my websites include: ibmathsresources.com and intermathematics.com. These are used by millions of students for IA ideas and support IB teachers across hundreds of schools worldwide. I have led webinars for IB teachers on the coursework process and have written hundreds of blog posts and articles exploring interesting coursework ideas. I thought it was time to make a course to share this with the IB community - I hope it is useful!
