Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65872, here are decompositions:
- 5 + 65867 = 65872
- 29 + 65843 = 65872
- 41 + 65831 = 65872
- 83 + 65789 = 65872
- 173 + 65699 = 65872
- 239 + 65633 = 65872
- 263 + 65609 = 65872
- 293 + 65579 = 65872
Showing the first eight; more decompositions exist.
