They are: 61+67 = 128 or if you mean 29+37 = 66
Sure. All composite numbers can be written as a product of primes. It shouldn't be tough to find a composite number that's the sum of three other composite numbers. Let's try 30. 2 x 3 x 5 = 30 Product of primes, check. 6 (2 x 3) + 10 (2 x 5) + 14 (2 x 7) = 30 Sum of three products of primes, check.
There are not three odd primes with the sum of 14. The sum of three odd primes will be an odd number.
The sum of two odd primes is always an even answer or number.
No, the sum of a prime number and a composite number is not always even.
This question cannot be answered because three odd primes always have an odd number for their sum.

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.
3 + 2 = 5 = 7 - 2

You can figure out the "composite numbers" from any table of primes - all the positive integers that are not prime numbers are composite (the number one should also be excluded). The first four composite numbers are:4, 6, 8, 9
