A mirror prime.
2*72 = 98Surely a squared number is not a prime number?Another answer:19+79 = 98
Here are some:13, 3117, 7137, 7379, 97107, 701
2 is the only even prime number, and it can be added to several odd numbers to make another prime number.For example:5 + 2 = 711 + 2 = 1317 + 2 = 1941 + 2 = 43
None. 251 is a prime number.
Numbers cannot "make" another number prime. If you are looking for the prime factorization of 56, it is 23 * 7.

Numbers never end. You can always continue to add another digit to a number and make it larger. Because this is the case, you can continue to look forward forever for prime numbers. The difference/distance between the numbers may grow, but prime numbers will continue to appear.
Two is the only even prime number. When you add an odd number to another odd number, you get an even number. When you add an even number to an odd number, you get an odd number. 91 is an odd number, therefore the answer is 2 and 89.

By dividing it by a number that will make the outcome prime.
None. 251 is a prime number.
The concepts of "prime numbers" and "composite numbers" make sense for integers (whole numbers), not for arbitrary real numbers.
7 is a prime number; its only prime factor is 7.
