Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145834, here are decompositions:
- 5 + 145829 = 145834
- 11 + 145823 = 145834
- 113 + 145721 = 145834
- 131 + 145703 = 145834
- 173 + 145661 = 145834
- 191 + 145643 = 145834
- 197 + 145637 = 145834
- 233 + 145601 = 145834
Showing the first eight; more decompositions exist.
