Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125928, here are decompositions:
- 7 + 125921 = 125928
- 29 + 125899 = 125928
- 31 + 125897 = 125928
- 41 + 125887 = 125928
- 107 + 125821 = 125928
- 137 + 125791 = 125928
- 139 + 125789 = 125928
- 151 + 125777 = 125928
Showing the first eight; more decompositions exist.
