Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18456, here are decompositions:
- 5 + 18451 = 18456
- 13 + 18443 = 18456
- 17 + 18439 = 18456
- 23 + 18433 = 18456
- 29 + 18427 = 18456
- 43 + 18413 = 18456
- 59 + 18397 = 18456
- 89 + 18367 = 18456
Showing the first eight; more decompositions exist.
