Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145726, here are decompositions:
- 3 + 145723 = 145726
- 5 + 145721 = 145726
- 17 + 145709 = 145726
- 23 + 145703 = 145726
- 47 + 145679 = 145726
- 83 + 145643 = 145726
- 89 + 145637 = 145726
- 137 + 145589 = 145726
Showing the first eight; more decompositions exist.
