Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125782, here are decompositions:
- 5 + 125777 = 125782
- 29 + 125753 = 125782
- 71 + 125711 = 125782
- 89 + 125693 = 125782
- 113 + 125669 = 125782
- 131 + 125651 = 125782
- 191 + 125591 = 125782
- 311 + 125471 = 125782
Showing the first eight; more decompositions exist.
