Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127918, here are decompositions:
- 5 + 127913 = 127918
- 41 + 127877 = 127918
- 59 + 127859 = 127918
- 101 + 127817 = 127918
- 137 + 127781 = 127918
- 179 + 127739 = 127918
- 191 + 127727 = 127918
- 227 + 127691 = 127918
Showing the first eight; more decompositions exist.
