Question

- if p and k are prims than p=2a+1 and k=2b+1 ,
with a and b naturale numbers graters or equales 1,
so than p+k=(2a+1)+(2b+1)=2a+2b+2=2(a+b+1) so from this resulted that the sum of two primes is always even.
- so than there is p+k=2(a+b+1)

True or False ?

Answer 1

your definitions for p & k don't allow them to be 2... which is prime

Answer 2

false

Answer 3

2+3= 5 , which is odd
if p & k are greater than 2 and prime, only then their sums must be even

Answer 4

p and k are always odd, but not always prime.
However, the sum of p and k are always even number

Answer 5

yes sure sorry p and k are primes grater than 2
so than is true ?

Answer 6

so i think that this wann to be the prove of definition that the sum of two primes grater than two will be always even

this is true ?

Answer 7

Yes

Answer 8

All prime numbers greater than 2 are odd.
Sum of two odd numbers is even.
So sum of 2 prime #s greater than 2 is even
