Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7876, here are decompositions:
- 3 + 7873 = 7876
- 23 + 7853 = 7876
- 47 + 7829 = 7876
- 53 + 7823 = 7876
- 59 + 7817 = 7876
- 83 + 7793 = 7876
- 149 + 7727 = 7876
- 173 + 7703 = 7876
Showing the first eight; more decompositions exist.
