Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18346, here are decompositions:
- 5 + 18341 = 18346
- 17 + 18329 = 18346
- 59 + 18287 = 18346
- 89 + 18257 = 18346
- 113 + 18233 = 18346
- 197 + 18149 = 18346
- 227 + 18119 = 18346
- 257 + 18089 = 18346
Showing the first eight; more decompositions exist.
