Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40868, here are decompositions:
- 19 + 40849 = 40868
- 67 + 40801 = 40868
- 97 + 40771 = 40868
- 109 + 40759 = 40868
- 229 + 40639 = 40868
- 241 + 40627 = 40868
- 271 + 40597 = 40868
- 277 + 40591 = 40868
Showing the first eight; more decompositions exist.
