Show that every even natural number grater than $2$ can be expressed as a sum of two prime numbers. No idea how to prove this. Can you help? thanks

Let me know if you find a proof of this. We can publish it together :-). – user17762 May 2 '13 at 14:55

Tough course you are taking, if this is homework! Solving it would put you on the front pages of newspapers. – André Nicolas May 2 '13 at 14:59
@AndréNicolas: Some of the conjectures in the past were solved by mistake in the past.(Teachers left them as open problems in home assignments). – Inceptio May 2 '13 at 15:06

This is known as Goldbach's conjecture. This still remains unproved till date. I bet you will make a great fame if you find the proof. All the best with that.:)
