If you're talking about which two prime numbers added together equals to 19, then the answer is 2 and 17. They are both prime numbers, and they add up to be 19.
There are several prime numbers that add up to 144 and of it is 71+73 =144
2, 3, 5, 7, 11, 29, 41
Add them together.
The two prime numbers that can be added together to make 54 are 7 and 47. Both 7 and 47 are prime, and their sum equals 54. There are no other pairs of prime numbers that also add up to 54.
You find the first 20 prime numbers and add them together. There is no formula for generating a sequence of prime numbers and so none for the series of their sums.You find the first 20 prime numbers and add them together.

No two prime numbers satisfy that request.

You can get another prime (only if one of the numbers added is 2), for example, 101 + 2 = 103. If you add together two odd prime numbers, you will get an even number, which will not be a prime number. (An even number is a number that is divisible by 2; if such a number is greater than 2, it is not a prime number.)
