Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20224, here are decompositions:
- 5 + 20219 = 20224
- 23 + 20201 = 20224
- 41 + 20183 = 20224
- 47 + 20177 = 20224
- 101 + 20123 = 20224
- 107 + 20117 = 20224
- 173 + 20051 = 20224
- 227 + 19997 = 20224
Showing the first eight; more decompositions exist.
