Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31766, here are decompositions:
- 37 + 31729 = 31766
- 43 + 31723 = 31766
- 67 + 31699 = 31766
- 79 + 31687 = 31766
- 103 + 31663 = 31766
- 109 + 31657 = 31766
- 139 + 31627 = 31766
- 193 + 31573 = 31766
Showing the first eight; more decompositions exist.
