Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68250, here are decompositions:
- 11 + 68239 = 68250
- 23 + 68227 = 68250
- 31 + 68219 = 68250
- 37 + 68213 = 68250
- 41 + 68209 = 68250
- 43 + 68207 = 68250
- 79 + 68171 = 68250
- 89 + 68161 = 68250
Showing the first eight; more decompositions exist.
