Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40942, here are decompositions:
- 3 + 40939 = 40942
- 59 + 40883 = 40942
- 89 + 40853 = 40942
- 101 + 40841 = 40942
- 113 + 40829 = 40942
- 179 + 40763 = 40942
- 191 + 40751 = 40942
- 233 + 40709 = 40942
Showing the first eight; more decompositions exist.
