Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68936, here are decompositions:
- 19 + 68917 = 68936
- 37 + 68899 = 68936
- 73 + 68863 = 68936
- 193 + 68743 = 68936
- 199 + 68737 = 68936
- 223 + 68713 = 68936
- 277 + 68659 = 68936
- 397 + 68539 = 68936
Showing the first eight; more decompositions exist.
