Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67728, here are decompositions:
- 5 + 67723 = 67728
- 19 + 67709 = 67728
- 29 + 67699 = 67728
- 97 + 67631 = 67728
- 109 + 67619 = 67728
- 127 + 67601 = 67728
- 139 + 67589 = 67728
- 149 + 67579 = 67728
Showing the first eight; more decompositions exist.
