Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137968, here are decompositions:
- 11 + 137957 = 137968
- 41 + 137927 = 137968
- 59 + 137909 = 137968
- 101 + 137867 = 137968
- 137 + 137831 = 137968
- 191 + 137777 = 137968
- 197 + 137771 = 137968
- 269 + 137699 = 137968
Showing the first eight; more decompositions exist.
