Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125722, here are decompositions:
- 5 + 125717 = 125722
- 11 + 125711 = 125722
- 29 + 125693 = 125722
- 53 + 125669 = 125722
- 71 + 125651 = 125722
- 83 + 125639 = 125722
- 101 + 125621 = 125722
- 131 + 125591 = 125722
Showing the first eight; more decompositions exist.
