Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188968, here are decompositions:
- 11 + 188957 = 188968
- 29 + 188939 = 188968
- 41 + 188927 = 188968
- 107 + 188861 = 188968
- 137 + 188831 = 188968
- 167 + 188801 = 188968
- 239 + 188729 = 188968
- 257 + 188711 = 188968
Showing the first eight; more decompositions exist.
