Textbook P8 #24 :D

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. The even numbers after 2 are 4,6,8,10 and so on. So if I had to add to prime numbers to have a sum of the numbers, i have to work out like this:
4=2+2
6=3+3
8=2+3+3
10=5+5

2, 3,and 5 are prime numbers, so all the other even numbers should also be expressed as a sum of prime numbers.
