Textbook: Brainworks (p8) Q24(b) A mathematician proposed that
"Every even number greater than 2 can
be expressed as a sum of two prime
numbers." Do you agree? Why?
I don't agree so.4 is an even number
however it is only formed by two 2s.
In this way,it is considered as only using
one prime number hence not every
single even number can be expressed
as a sum of two prime numbers.
