Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47942, here are decompositions:
- 3 + 47939 = 47942
- 31 + 47911 = 47942
- 61 + 47881 = 47942
- 73 + 47869 = 47942
- 151 + 47791 = 47942
- 163 + 47779 = 47942
- 199 + 47743 = 47942
- 229 + 47713 = 47942
Showing the first eight; more decompositions exist.
