Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68904, here are decompositions:
- 5 + 68899 = 68904
- 7 + 68897 = 68904
- 13 + 68891 = 68904
- 23 + 68881 = 68904
- 41 + 68863 = 68904
- 83 + 68821 = 68904
- 113 + 68791 = 68904
- 127 + 68777 = 68904
Showing the first eight; more decompositions exist.
