Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40186, here are decompositions:
- 17 + 40169 = 40186
- 23 + 40163 = 40186
- 59 + 40127 = 40186
- 149 + 40037 = 40186
- 173 + 40013 = 40186
- 197 + 39989 = 40186
- 233 + 39953 = 40186
- 257 + 39929 = 40186
Showing the first eight; more decompositions exist.
