Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47842, here are decompositions:
- 5 + 47837 = 47842
- 23 + 47819 = 47842
- 101 + 47741 = 47842
- 131 + 47711 = 47842
- 233 + 47609 = 47842
- 251 + 47591 = 47842
- 383 + 47459 = 47842
- 401 + 47441 = 47842
Showing the first eight; more decompositions exist.
