Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127968, here are decompositions:
- 17 + 127951 = 127968
- 37 + 127931 = 127968
- 47 + 127921 = 127968
- 101 + 127867 = 127968
- 109 + 127859 = 127968
- 131 + 127837 = 127968
- 149 + 127819 = 127968
- 151 + 127817 = 127968
Showing the first eight; more decompositions exist.
