Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18358, here are decompositions:
- 5 + 18353 = 18358
- 17 + 18341 = 18358
- 29 + 18329 = 18358
- 47 + 18311 = 18358
- 71 + 18287 = 18358
- 89 + 18269 = 18358
- 101 + 18257 = 18358
- 107 + 18251 = 18358
Showing the first eight; more decompositions exist.
