Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145960, here are decompositions:
- 11 + 145949 = 145960
- 29 + 145931 = 145960
- 131 + 145829 = 145960
- 137 + 145823 = 145960
- 239 + 145721 = 145960
- 251 + 145709 = 145960
- 257 + 145703 = 145960
- 281 + 145679 = 145960
Showing the first eight; more decompositions exist.
