MiddleOne is an odd number old

MiddleOne is an odd number old today. Unlike OldestOne he's not a prime number old.

His age has two digits. The sum of the two digits is an even number, as is the sum of the two digits of EldestOne's age.

Adding these two numbers together gives you a two digit number that is one less than MiddleOne's age. Subtracting them gives you an even prime number.
