Goldbach to and fro
The Goldbach conjecture states that
"every even number greater than 2 can be written as the sum of two primes."
The converse, namely
"the sum of any two primes greater than 2 is an even number"
is obvious.
Use this applet to explore the Goldbach conjecture.
[the Prime Locator allow you to slide a point on the number line.
The position of the point on the number line is printed in RED when the point is on a prime number.]
