That isn't possible. The sum of three odd numbers will always be odd. You can make the sum of 3 prime numbers equal to 32 if one of them is 2 (which is not odd).
The numbers 32 and 1 (32 x 1 = 32) sum to 33. The numbers 4 and 8 (4 x 8 = 32) sum to 12 The numbers 2 and 16 (2 x 16 = 32) sum to 18. There are no other factors which are integers, so 32 and 1 is the answer.

There are no two prime numbers that add up to 32. The only even prime number is 2, and since the sum of two odd prime numbers is even, the only possible pair would involve 2. However, 2 plus any odd prime number will not equal 32, as the result would exceed 32 when adding another odd prime.
2, 7, and 89 are three prime numbers whose sum is 98.

The numbers 4 and 8 (4 x 8 = 32) sum to 12. The numbers 2 and 16 (2 x 16 = 32) sum to 18. There are no other factors which are integers, so 4 and 8 is the answer.
