Answer:

picture from Goldbach's conjecture.

Step-by-step explanation:

Goldbach's conjecture is one of the oldest and best-known unsolved problems in number theory and all of mathematics. It states:

The conjecture has been shown to hold for all integers less than 4 × 10^18, but remains unproven despite considerable effort.
