Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18292, here are decompositions:
- 3 + 18289 = 18292
- 5 + 18287 = 18292
- 23 + 18269 = 18292
- 41 + 18251 = 18292
- 59 + 18233 = 18292
- 101 + 18191 = 18292
- 149 + 18143 = 18292
- 173 + 18119 = 18292
Showing the first eight; more decompositions exist.
