All prime numbers greater than 2 are odd numbers. For an odd prime to be written as the sum of two primes, one of the primes must be 2 because two odd primes will produce an even sum. 11 cannot be written as the sum of two primes. 13 = 2 + 11. 17 cannot be written as the sum of two primes. 19 = 2 + 17.

The sum of two odd primes is always an even answer or number.

19 and 43 are two primes having 62 as their sum.

16

It is: 2+13 = 15

It is: 19+79 = 98

There are not three odd primes with the sum of 14. The sum of three odd primes will be an odd number.

There are no two primes whose sum is 209.

It is not. Of the infinitely many primes only one (the number 2) is even, the rest are all odd. The sum of any two primes other than 2 is even and therefore not a prime. If one of the primes in the sum is 2 then the sum is a prime only if the other is the lower of a pair of twin primes. So, while it is possible, it is certainly more likely that the sum is a composite.

Each one of them can be expressed as a sum of two primes.

12=5+7

Three of them.

The sum of the primes between these two is 462.

59 and 53 are the two largest primes less than 60. 59+53 = 112

Yes. all prime numbers are odd numbers so the sum of any two will be an even number.

Goldbach's conjecture says that every even number greater than two can be expressed as the sum of 2 primes. If 30 could not be expressed as the sum of two primes, then this would disprove the conjecture. As it is, 30 can be expressed as the sum of two primes. You can express it as 11+19. Thus, Goldbach's conjecture holds in this case.

There are no two primes whose sum is 221.
