Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145792, here are decompositions:
- 71 + 145721 = 145792
- 83 + 145709 = 145792
- 89 + 145703 = 145792
- 113 + 145679 = 145792
- 131 + 145661 = 145792
- 149 + 145643 = 145792
- 191 + 145601 = 145792
- 281 + 145511 = 145792
Showing the first eight; more decompositions exist.
