Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57842, here are decompositions:
- 3 + 57839 = 57842
- 13 + 57829 = 57842
- 61 + 57781 = 57842
- 163 + 57679 = 57842
- 193 + 57649 = 57842
- 241 + 57601 = 57842
- 271 + 57571 = 57842
- 283 + 57559 = 57842
Showing the first eight; more decompositions exist.
