Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18124, here are decompositions:
- 3 + 18121 = 18124
- 5 + 18119 = 18124
- 47 + 18077 = 18124
- 83 + 18041 = 18124
- 137 + 17987 = 18124
- 167 + 17957 = 18124
- 233 + 17891 = 18124
- 317 + 17807 = 18124
Showing the first eight; more decompositions exist.
