Can't exactly adjust the offset in an op-amp circuit

I also want to add a 1.65V (3.3V/2) offset to the non-inverting pin so I can pull the signal to -1.65/+1.65 V range before applying gain, but the op-amp seems to just not add the exact offset voltage I'm … I've checked a few schematics for offset adjustable op-amp circuits but wasn't able to comprehend. …

Can't exactly adjust the offset in an op-amp circuit

Using the same circuit I posted in the original question, I just tinkered with the resistor values to have the intended offset and gain. … R3 and R2 represents a 10k potentiometer, to adjust the offset. R5 and R1 represents another 10k potentiometer, to adjust gain. So the weird values in the resistors are actually achievable. …
