Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67856, here are decompositions:
- 3 + 67853 = 67856
- 13 + 67843 = 67856
- 37 + 67819 = 67856
- 67 + 67789 = 67856
- 73 + 67783 = 67856
- 79 + 67777 = 67856
- 97 + 67759 = 67856
- 157 + 67699 = 67856
Showing the first eight; more decompositions exist.
