trial and error, also called guess and check, but not quite
let x = 1st odd prime, and y = 2nd odd prime
the y can be 1,3,5,7,11,13,17,19,23,29,31
then x+y = 36, or x = 36 - y, by substitution
x = 36 - 1 = 35 not prime so not a solution
x = 36 - 3 = 33 not prime
x = 36 - 5 = 31 prime
x = 36 - 7 = 29 prime
x = 36 - 11 = 25 not prime
x = 36 - 13 = 23 prime
x = 36 - 17 = 19 prime
x = 36 - 19 = 17 prime (but a repeat of another solution)
so (5+31), and (7+29), and (13+23), and (17+19) are all solutions
For your question about the method, maybe it is called the method of exhaustion. List all possibilities for one number and exhaust (solve and check) for all other solutions.
There are not three odd primes with the sum of 14. The sum of three odd primes will be an odd number.
This question cannot be answered because three odd primes always have an odd number for their sum.
The sum of two odd primes is always an even answer or number.
The prime numbers 3 an 7 are both odd and sum to 10.
To make odd numbers total an odd number, you have to have an odd number of them. 7 + 13 + 43 = 63

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 prime numbers 3 an 7 are both odd and sum to 10.
To make odd numbers total an odd number, you have to have an odd number of them. 7 + 13 + 43 = 63
23 + 31 = 54
Not true. 2 + 3 = 5, where all three are primes. One of the primes in the sum must be 2, otherwise both primes would be odd and their sum would be even (and >2) and therefore not prime. Such primes: p and p+2 [3 and 5 in the above example] are known as twin primes and there are infiitely many twin primes.
It can be and they are: 53+79 = 132
To express the numbers 46 and 38 as the sum of two odd primes, you can use the following combinations: For 46: 46 = 43 (a prime number) + 3 (a prime number) 46 = 41 (a prime number) + 5 (a prime number) For 38: 38 = 37 (a prime number) + 1 (a prime number) 38 = 31 (a prime number) + 7 (a prime number) So, 46 can be expressed as the sum of two odd primes in two ways, and 38 can also be expressed as the sum of two odd primes in two ways.
