Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68400, here are decompositions:
- 11 + 68389 = 68400
- 29 + 68371 = 68400
- 71 + 68329 = 68400
- 89 + 68311 = 68400
- 139 + 68261 = 68400
- 173 + 68227 = 68400
- 181 + 68219 = 68400
- 191 + 68209 = 68400
Showing the first eight; more decompositions exist.
