it can be 22 44 66 or 88, yes that is true, but it can also be 20 22 24 26 28, and so on because the person clearly says that the number has two digits and both digits are even, but the person did not say that the even numbers had to be the same

The number is 19.
The 2-digit number must be 20, because it is the only 2-digit number whose sum of its two even digits, 2 + 0 = 2, is greater than the product of its two even digits, 2 x 0 = 0. Moreover, 20 is a product of the two consecutive integers 4 and 5.
It is even. Both numbers end with odd digits and two odd digits always add to an even number. You can see that is the case in this instance.377 + 87 = 464
73 is the largest two-digit number that is prime and has prime numbers for both of its digits.
The number is 19.

19.
The only two digit numbers whose digits add up to 17 are 89 and 98. Since 98 is an even number, 89 is prime.
