Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67942, here are decompositions:
- 3 + 67939 = 67942
- 11 + 67931 = 67942
- 41 + 67901 = 67942
- 59 + 67883 = 67942
- 89 + 67853 = 67942
- 113 + 67829 = 67942
- 179 + 67763 = 67942
- 191 + 67751 = 67942
Showing the first eight; more decompositions exist.
