Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31706, here are decompositions:
- 7 + 31699 = 31706
- 19 + 31687 = 31706
- 43 + 31663 = 31706
- 79 + 31627 = 31706
- 139 + 31567 = 31706
- 163 + 31543 = 31706
- 193 + 31513 = 31706
- 229 + 31477 = 31706
Showing the first eight; more decompositions exist.
