Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18310, here are decompositions:
- 3 + 18307 = 18310
- 23 + 18287 = 18310
- 41 + 18269 = 18310
- 53 + 18257 = 18310
- 59 + 18251 = 18310
- 167 + 18143 = 18310
- 179 + 18131 = 18310
- 191 + 18119 = 18310
Showing the first eight; more decompositions exist.
