Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27942, here are decompositions:
- 23 + 27919 = 27942
- 41 + 27901 = 27942
- 59 + 27883 = 27942
- 139 + 27803 = 27942
- 149 + 27793 = 27942
- 151 + 27791 = 27942
- 163 + 27779 = 27942
- 179 + 27763 = 27942
Showing the first eight; more decompositions exist.
