Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13942, here are decompositions:
- 11 + 13931 = 13942
- 29 + 13913 = 13942
- 41 + 13901 = 13942
- 59 + 13883 = 13942
- 83 + 13859 = 13942
- 101 + 13841 = 13942
- 113 + 13829 = 13942
- 179 + 13763 = 13942
Showing the first eight; more decompositions exist.
