To say a thing like that is to confirm that the distinction between odd and even is more of a language concept than a numerical concept. You could also say that it is significant that among all the even numbers, 2 is the only prime one, compared with quite a lot of primes among the odd numbers. The real anomaly with 2 as a prime is because it is so small. For all other primes P, the number 1 behaves in a certain way relative to it, and the number P-1 behaves in a certain other way. When P is 2, the numbers 1 and P-1 are identical.

87 is not a prime number, because it can be divided by 3 to give a positive integer (29)
Nice question :D

87 can be divided by 3, the multiples of 3 are simple you just ad the digits and see if the sum is a simple multiple of 3, 8+7=15 and 15 is multiple of 3

If a number is not even, then next best thing is to check divisibility by 3. The test is add the digits of the number, in this case,8+7 = 15, if that number is divisible by 3, then the original number is as well.
