Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68938, here are decompositions:
- 11 + 68927 = 68938
- 29 + 68909 = 68938
- 41 + 68897 = 68938
- 47 + 68891 = 68938
- 59 + 68879 = 68938
- 167 + 68771 = 68938
- 227 + 68711 = 68938
- 239 + 68699 = 68938
Showing the first eight; more decompositions exist.
