Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68930, here are decompositions:
- 3 + 68927 = 68930
- 13 + 68917 = 68930
- 31 + 68899 = 68930
- 67 + 68863 = 68930
- 109 + 68821 = 68930
- 139 + 68791 = 68930
- 163 + 68767 = 68930
- 181 + 68749 = 68930
Showing the first eight; more decompositions exist.
