Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125904, here are decompositions:
- 5 + 125899 = 125904
- 7 + 125897 = 125904
- 17 + 125887 = 125904
- 41 + 125863 = 125904
- 83 + 125821 = 125904
- 101 + 125803 = 125904
- 113 + 125791 = 125904
- 127 + 125777 = 125904
Showing the first eight; more decompositions exist.
