The

chinese mathematican Chen Jing-Rung has made a big step towards solving the

Goldbach's conjecture in 1966. He was able to prove that each

even number bigger than 2 is the

sum of a

prime number and the

product of two prime numbers. So 20 is the sum of 5 and 15, what is the product of 5 and 3. This seems to be very near to the prove of Goldbach's conjecture but in the last thirty years no one was able to make the last step.

The american publishing house "Bloomsbury" and the english "Faber" offer a prize of one million US Dollar to the person who publishes the prove in the next four years.
