Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31842, here are decompositions:
- 43 + 31799 = 31842
- 71 + 31771 = 31842
- 73 + 31769 = 31842
- 101 + 31741 = 31842
- 113 + 31729 = 31842
- 179 + 31663 = 31842
- 193 + 31649 = 31842
- 199 + 31643 = 31842
Showing the first eight; more decompositions exist.
