Prime numbers

A mathematician proposed that "Every even number greater than 2 can be expressed as a sum of prime numbers."Do you agree? Why?
I agree. According to the Goldbalch's theory, every even number greater than two can be expressed as a sum of two primes. For example...
and so on...
Besides that, any even number more than 5 can be written as a sum of three primes. This magical equation is one of the oldest unsolved problems in number theory.

    Well done! And you've explained your reasoning with examples.

    It's an interesting find for the even number that are more than 5. Is there any proof on this?
    Perhaps you could give a couple of example on that, too?
