I understand. But there is a process that we could follow till we get answer.
In case of 40 the following may be follwed:
40
40/2
20 + 20 = 40
(20-1) + (20+1) = 40
19 + 21  = 40 [21 is not Odd Prime Number]
In that case I'll again +/- 2
(19-2) + (21+2) = 40
17 + 23 = 40.

I would like to know where any such process to find three Odd Prime.

Thank you.

In case of to express a number as the sum of two odd primes, we divide the number by 2 and we get two numbers.  Then we add 1 with a derived number and minus 1 from another derived number. Such as:

24

24 / 2 = 12

12 + 12 = 24

(12+1) + (12-1) = 24

13 + 11 = 24.

I would to like to know how to calculate and express a number as the sum of three odd primes. Say 53.
