Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40066, here are decompositions:
- 3 + 40063 = 40066
- 29 + 40037 = 40066
- 53 + 40013 = 40066
- 83 + 39983 = 40066
- 113 + 39953 = 40066
- 137 + 39929 = 40066
- 179 + 39887 = 40066
- 197 + 39869 = 40066
Showing the first eight; more decompositions exist.
