Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18424, here are decompositions:
- 11 + 18413 = 18424
- 23 + 18401 = 18424
- 53 + 18371 = 18424
- 71 + 18353 = 18424
- 83 + 18341 = 18424
- 113 + 18311 = 18424
- 137 + 18287 = 18424
- 167 + 18257 = 18424
Showing the first eight; more decompositions exist.
