Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67808, here are decompositions:
- 7 + 67801 = 67808
- 19 + 67789 = 67808
- 31 + 67777 = 67808
- 67 + 67741 = 67808
- 109 + 67699 = 67808
- 157 + 67651 = 67808
- 229 + 67579 = 67808
- 241 + 67567 = 67808
Showing the first eight; more decompositions exist.
