Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18150, here are decompositions:
- 7 + 18143 = 18150
- 17 + 18133 = 18150
- 19 + 18131 = 18150
- 23 + 18127 = 18150
- 29 + 18121 = 18150
- 31 + 18119 = 18150
- 53 + 18097 = 18150
- 61 + 18089 = 18150
Showing the first eight; more decompositions exist.
