Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125972, here are decompositions:
- 13 + 125959 = 125972
- 31 + 125941 = 125972
- 43 + 125929 = 125972
- 73 + 125899 = 125972
- 109 + 125863 = 125972
- 151 + 125821 = 125972
- 181 + 125791 = 125972
- 229 + 125743 = 125972
Showing the first eight; more decompositions exist.
