Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68238, here are decompositions:
- 11 + 68227 = 68238
- 19 + 68219 = 68238
- 29 + 68209 = 68238
- 31 + 68207 = 68238
- 67 + 68171 = 68238
- 97 + 68141 = 68238
- 127 + 68111 = 68238
- 139 + 68099 = 68238
Showing the first eight; more decompositions exist.
