Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68878, here are decompositions:
- 59 + 68819 = 68878
- 101 + 68777 = 68878
- 107 + 68771 = 68878
- 149 + 68729 = 68878
- 167 + 68711 = 68878
- 179 + 68699 = 68878
- 191 + 68687 = 68878
- 239 + 68639 = 68878
Showing the first eight; more decompositions exist.
