You don't have all the time for it. There a countdown timer... But don't get angry, most people can't pass even 100...

At the end of the game you will have your score and estimated age of your brain based on empirical worldwide measurements.

A PRIME number is a natural number GREATER than 1 that has NO positive divisors other than 1 and ITSELF. A natural number greater than 1 that is not a prime number is called a composite number.

Example: 2, 3, 5, 7 are primes, but 4, 6 and 9 are not!

BTW, Goldbach's conjecture (that this game is based on) is one of the oldest and best-known unsolved problems in number theory and in all of mathematics.

It states: Every even integer greater than 2 can be expressed as the sum of two PRIMES!

Please, read the instructions! It's not another simple calculator toy! The game is for really smart people to help develop their math skills! Remember, this saga is all about primes! Be the prime numbers master.
