258 + 1 is equal to the integer 288230376151711745 which, by ending in a 5, is obviously divisible by 5 and thus an integer. (258 + 1)/5 is also the certified prime 57646075230342323.
See correction in later post, though 57646075230342323 is a certified prime, (258 + 1)/5 is not as it is equal to 57646075230342349, a composite number.
