Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127798, here are decompositions:
- 17 + 127781 = 127798
- 59 + 127739 = 127798
- 71 + 127727 = 127798
- 89 + 127709 = 127798
- 107 + 127691 = 127798
- 149 + 127649 = 127798
- 191 + 127607 = 127798
- 197 + 127601 = 127798
Showing the first eight; more decompositions exist.
