Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68320, here are decompositions:
- 41 + 68279 = 68320
- 59 + 68261 = 68320
- 101 + 68219 = 68320
- 107 + 68213 = 68320
- 113 + 68207 = 68320
- 149 + 68171 = 68320
- 173 + 68147 = 68320
- 179 + 68141 = 68320
Showing the first eight; more decompositions exist.
