Every even number is the sum of two primes
WebSuppose that every even natural number greater that 2 2 2 is the sum of two primes. Let m m m be an odd natural number greater than 5 5 5. Then m − 3 m-3 m − 3 is an even natural number greater than 5 5 5. Then m − 3 m-3 m − 3 is an even natural number greater than 2 2 2. Then there are two primes p 1 p_{_{1}} p 1 and p 2 p_{_{2}} p 2 ... WebNov 14, 2015 · As the sum of two odd numbers is even (and $1007$ is odd) one of $x,y$ must be even. Wlog. $x$ is even, and as $2$ is the only even prime we conclude $x=2$ and then $y=1007-2=1005=5\cdot 201$ is not prime, contradiction." - Then again, some folks would say that $-2$ is also a prime. In that case $1007= (-2)+1009$ is a solution! – …
