Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18342, here are decompositions:
- 13 + 18329 = 18342
- 29 + 18313 = 18342
- 31 + 18311 = 18342
- 41 + 18301 = 18342
- 53 + 18289 = 18342
- 73 + 18269 = 18342
- 89 + 18253 = 18342
- 109 + 18233 = 18342
Showing the first eight; more decompositions exist.
