Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68784, here are decompositions:
- 7 + 68777 = 68784
- 13 + 68771 = 68784
- 17 + 68767 = 68784
- 41 + 68743 = 68784
- 47 + 68737 = 68784
- 71 + 68713 = 68784
- 73 + 68711 = 68784
- 97 + 68687 = 68784
Showing the first eight; more decompositions exist.
