Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65818, here are decompositions:
- 29 + 65789 = 65818
- 41 + 65777 = 65818
- 89 + 65729 = 65818
- 101 + 65717 = 65818
- 131 + 65687 = 65818
- 167 + 65651 = 65818
- 239 + 65579 = 65818
- 281 + 65537 = 65818
Showing the first eight; more decompositions exist.
