Assuming you're intending it to be an attenuator?, the values are completely wrong.
However, as PIC inputs are almost all diode protected, a simple series resistor is all that's actually required - try a 15K or something like that, or two 15K's in the circuit you already have.

hi,
The internal parasitic diodes will take care of any moderate excess voltage.
If you wish, 15K in the top and 10K in bottom,,,, [10k/25k] *12 = 4.8V
