Oxygen 12 destabilized nuclear structure
Nuclear structure of

Oxygen 12 

(half life = 580 ys). Move mouse on image for Oxygen 12 destabilized form

Blue toruses = 12 protons
Red toruses = 4 nuclear electrons

Atomic number of O (8) = protons (12) - nuclear electrons (4)

Oxygen 12 decomposes by 2 proton emission (from left and right side position) of Oxygen 12 destabilized form through Carbon 10

Carbon 10 undergo a transformation of b+ electron capture (into the central position) of recombinant structure forming Boron 10 stable nucleus.
The other component of the participant photon decomposition, the residual positron emitted.
