Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31876, here are decompositions:
- 3 + 31873 = 31876
- 17 + 31859 = 31876
- 29 + 31847 = 31876
- 59 + 31817 = 31876
- 83 + 31793 = 31876
- 107 + 31769 = 31876
- 149 + 31727 = 31876
- 227 + 31649 = 31876
Showing the first eight; more decompositions exist.
