Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67866, here are decompositions:
- 13 + 67853 = 67866
- 23 + 67843 = 67866
- 37 + 67829 = 67866
- 47 + 67819 = 67866
- 59 + 67807 = 67866
- 83 + 67783 = 67866
- 89 + 67777 = 67866
- 103 + 67763 = 67866
Showing the first eight; more decompositions exist.
