Even Pairs

Have the function EvenPairs(str) take the str parameter being passed and determine if a pair of adjacent even numbers exists anywhere in the string. If a pair exists, return the string true, otherwise return false. For example: if str is "f178svg3k19k46" then there are two even numbers at the end of the string, "46" so your program should return the string true. Another example: if str is "7r5gg812" then the pair is "812" (8 and 12) so your program should return the string true.
