Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31746, here are decompositions:
- 5 + 31741 = 31746
- 17 + 31729 = 31746
- 19 + 31727 = 31746
- 23 + 31723 = 31746
- 47 + 31699 = 31746
- 59 + 31687 = 31746
- 79 + 31667 = 31746
- 83 + 31663 = 31746
Showing the first eight; more decompositions exist.
