Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18162, here are decompositions:
- 13 + 18149 = 18162
- 19 + 18143 = 18162
- 29 + 18133 = 18162
- 31 + 18131 = 18162
- 41 + 18121 = 18162
- 43 + 18119 = 18162
- 73 + 18089 = 18162
- 101 + 18061 = 18162
Showing the first eight; more decompositions exist.
