Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543876, here are decompositions:
- 3 + 31543873 = 31543876
- 5 + 31543871 = 31543876
- 17 + 31543859 = 31543876
- 29 + 31543847 = 31543876
- 47 + 31543829 = 31543876
- 59 + 31543817 = 31543876
- 107 + 31543769 = 31543876
- 113 + 31543763 = 31543876
Showing the first eight; more decompositions exist.
