Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66898, here are decompositions:
- 47 + 66851 = 66898
- 89 + 66809 = 66898
- 101 + 66797 = 66898
- 107 + 66791 = 66898
- 149 + 66749 = 66898
- 197 + 66701 = 66898
- 269 + 66629 = 66898
- 281 + 66617 = 66898
Showing the first eight; more decompositions exist.
