Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145954, here are decompositions:
- 5 + 145949 = 145954
- 23 + 145931 = 145954
- 131 + 145823 = 145954
- 197 + 145757 = 145954
- 233 + 145721 = 145954
- 251 + 145703 = 145954
- 293 + 145661 = 145954
- 311 + 145643 = 145954
Showing the first eight; more decompositions exist.
