Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31884, here are decompositions:
- 11 + 31873 = 31884
- 37 + 31847 = 31884
- 67 + 31817 = 31884
- 113 + 31771 = 31884
- 157 + 31727 = 31884
- 163 + 31721 = 31884
- 197 + 31687 = 31884
- 227 + 31657 = 31884
Showing the first eight; more decompositions exist.
