Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68908, here are decompositions:
- 5 + 68903 = 68908
- 11 + 68897 = 68908
- 17 + 68891 = 68908
- 29 + 68879 = 68908
- 89 + 68819 = 68908
- 131 + 68777 = 68908
- 137 + 68771 = 68908
- 179 + 68729 = 68908
Showing the first eight; more decompositions exist.
