Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18282, here are decompositions:
- 13 + 18269 = 18282
- 29 + 18253 = 18282
- 31 + 18251 = 18282
- 53 + 18229 = 18282
- 59 + 18223 = 18282
- 71 + 18211 = 18282
- 83 + 18199 = 18282
- 101 + 18181 = 18282
Showing the first eight; more decompositions exist.
