No. In order for two factors (i.e. two numbers multiplied together) to result in an even number, at least one of the factors must be even. Except for "2" all prime numbers by definition must be odd numbers. 168/2 = 84. 84 is not prime. Therefore you are looking for 2 odd factors of 168. But this is a fruitless search as 2 odd numbers multiplied together will never result in an even number.

504/3 = 168 so the three numbers are 167, 168 and 169.504/3 = 168 so the three numbers are 167, 168 and 169.504/3 = 168 so the three numbers are 167, 168 and 169.504/3 = 168 so the three numbers are 167, 168 and 169.
These pairs of numbers when multiplied equal 168: (1, 168) (2, 84) (3, 56) (4, 42) (6, 28) (7, 24) (8, 21) (12, 14)
