No, when you parallel equal value resistors, you divide their resistance by their number. For example, if you parallel two 32K 1/2 watt resistors, the result will be a 16K resistor of 1 watt rating.
If you have no other choice, you can try paralleling four 120 K 1/2 watt resistors which will result in a 30K combination. Four 130K resistors will give you 32.5K. The combination of the four should be able to dissipate close to two watts.
Strictly speaking, the wattage rating of each resistor is determined when it is in free air, not bundled close together with others, which may reduce the air flow and the cooling effect. But for practical purposes, it should work fine since the actual wattage dissipated by the circuit is actually less than a full two watts.
