Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66942, here are decompositions:
- 11 + 66931 = 66942
- 19 + 66923 = 66942
- 23 + 66919 = 66942
- 53 + 66889 = 66942
- 59 + 66883 = 66942
- 79 + 66863 = 66942
- 89 + 66853 = 66942
- 101 + 66841 = 66942
Showing the first eight; more decompositions exist.
