Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78910, here are decompositions:
- 17 + 78893 = 78910
- 23 + 78887 = 78910
- 53 + 78857 = 78910
- 71 + 78839 = 78910
- 101 + 78809 = 78910
- 107 + 78803 = 78910
- 113 + 78797 = 78910
- 131 + 78779 = 78910
Showing the first eight; more decompositions exist.
