Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135942, here are decompositions:
- 5 + 135937 = 135942
- 13 + 135929 = 135942
- 29 + 135913 = 135942
- 31 + 135911 = 135942
- 43 + 135899 = 135942
- 83 + 135859 = 135942
- 101 + 135841 = 135942
- 113 + 135829 = 135942
Showing the first eight; more decompositions exist.
