Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47828, here are decompositions:
- 19 + 47809 = 47828
- 31 + 47797 = 47828
- 37 + 47791 = 47828
- 127 + 47701 = 47828
- 199 + 47629 = 47828
- 229 + 47599 = 47828
- 307 + 47521 = 47828
- 331 + 47497 = 47828
Showing the first eight; more decompositions exist.
