Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22928, here are decompositions:
- 7 + 22921 = 22928
- 67 + 22861 = 22928
- 151 + 22777 = 22928
- 211 + 22717 = 22928
- 229 + 22699 = 22928
- 277 + 22651 = 22928
- 307 + 22621 = 22928
- 379 + 22549 = 22928
Showing the first eight; more decompositions exist.
