Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67806, here are decompositions:
- 5 + 67801 = 67806
- 17 + 67789 = 67806
- 23 + 67783 = 67806
- 29 + 67777 = 67806
- 43 + 67763 = 67806
- 47 + 67759 = 67806
- 73 + 67733 = 67806
- 83 + 67723 = 67806
Showing the first eight; more decompositions exist.
