Express the composite numbers as the sum of two prime numbers -:

$30=.................+..................$

State true (T) of false (F):

$\left(i\right)$ The sum of primes cannot be a prime.

$\left(ii\right)$ The product of primes cannot be a prime.

$\left(iii\right)$ An even number is composite.

$\left(iv\right)$ Two consecutive numbers cannot be both primes.

$\left(v\right)$ Odd numbers cannot be composite.

$\left(vi\right)$ Odd numbers cannot be written as sum of primes.

$\left(vii\right)$ A number and its successor are always co-primes.
