Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127856, here are decompositions:
- 7 + 127849 = 127856
- 13 + 127843 = 127856
- 19 + 127837 = 127856
- 37 + 127819 = 127856
- 109 + 127747 = 127856
- 139 + 127717 = 127856
- 193 + 127663 = 127856
- 199 + 127657 = 127856
Showing the first eight; more decompositions exist.
