Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125790, here are decompositions:
- 13 + 125777 = 125790
- 37 + 125753 = 125790
- 47 + 125743 = 125790
- 53 + 125737 = 125790
- 59 + 125731 = 125790
- 73 + 125717 = 125790
- 79 + 125711 = 125790
- 83 + 125707 = 125790
Showing the first eight; more decompositions exist.
