There is no pair of prime numbers that sum to 123.
Proof :
Any two odd primes will sum to an even number, thus excluding 123 which is odd.
Since 2 is the only even prime, the only possible solution is 2 + 121 = 123.
But, 121 is not prime because it is 11 x 11.
A similar proof shows that there is no pair of primes whose difference is 123.
There are two primes that multiply to 123 : - 3 and 41.
