Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40270, here are decompositions:
- 17 + 40253 = 40270
- 29 + 40241 = 40270
- 101 + 40169 = 40270
- 107 + 40163 = 40270
- 233 + 40037 = 40270
- 239 + 40031 = 40270
- 257 + 40013 = 40270
- 281 + 39989 = 40270
Showing the first eight; more decompositions exist.
