Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47838, here are decompositions:
- 19 + 47819 = 47838
- 29 + 47809 = 47838
- 31 + 47807 = 47838
- 41 + 47797 = 47838
- 47 + 47791 = 47838
- 59 + 47779 = 47838
- 61 + 47777 = 47838
- 97 + 47741 = 47838
Showing the first eight; more decompositions exist.
