Understanding conservation of energy during generation of entanglement.

Single photons are struck on a BBO crystal.

In about 1 in a trillion of such collisions, two photons emerge.

1. Is the combined energy of the two photons exactly equal to the "pump/original" photon?

2. If a photon is the smallest quanta of energy, then how do we explain the fact that its energy has been split among two photons?

or

3. Are there two parts to the energy of a photon? i.e.

a) energy

taking the example of a ball --> the ball can be converted to energy

b) energy

taking the example of a ball --> the ball is moving at a certain velocity it caries some force/energy/momentum
