Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125970, here are decompositions:
- 7 + 125963 = 125970
- 11 + 125959 = 125970
- 29 + 125941 = 125970
- 37 + 125933 = 125970
- 41 + 125929 = 125970
- 43 + 125927 = 125970
- 71 + 125899 = 125970
- 73 + 125897 = 125970
Showing the first eight; more decompositions exist.
