Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127726, here are decompositions:
- 17 + 127709 = 127726
- 23 + 127703 = 127726
- 47 + 127679 = 127726
- 83 + 127643 = 127726
- 89 + 127637 = 127726
- 197 + 127529 = 127726
- 233 + 127493 = 127726
- 239 + 127487 = 127726
Showing the first eight; more decompositions exist.
