Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78876, here are decompositions:
- 19 + 78857 = 78876
- 23 + 78853 = 78876
- 37 + 78839 = 78876
- 53 + 78823 = 78876
- 67 + 78809 = 78876
- 73 + 78803 = 78876
- 79 + 78797 = 78876
- 89 + 78787 = 78876
Showing the first eight; more decompositions exist.
