Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104878, here are decompositions:
- 29 + 104849 = 104878
- 47 + 104831 = 104878
- 89 + 104789 = 104878
- 149 + 104729 = 104878
- 167 + 104711 = 104878
- 197 + 104681 = 104878
- 227 + 104651 = 104878
- 239 + 104639 = 104878
Showing the first eight; more decompositions exist.
