If by "equal up" you mean add up, there are at least two answers: (3, 7, 13, 31) and (5, 7, 11, 31).
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.

The only two prime numbers that add up to 24 are 11 and 13. Prime numbers are numbers greater than 1 that can only be divided by 1 and themselves without leaving a remainder. In this case, 11 and 13 are both prime numbers, and when added together, they equal 24.
2 and 17
There are no two prime numbers that add up to 48. The only even prime number is 2, and if we pair it with another prime number to equal 48, the second number would be 46, which is not prime. All other pairs of prime numbers will yield odd sums, making it impossible to find two primes that sum to an even number like 48.
As a product of its prime factors: 2*3*13 = 78
Not really. You just have to try different numbers. As to patterns, the probability of finding a prime goes down for higher numbers. The number of prime numbers up to a number "n" is roughly equal to n / ln(n), where ln() is the natural logarithm function.
