Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18132, here are decompositions:
- 5 + 18127 = 18132
- 11 + 18121 = 18132
- 13 + 18119 = 18132
- 43 + 18089 = 18132
- 71 + 18061 = 18132
- 73 + 18059 = 18132
- 83 + 18049 = 18132
- 89 + 18043 = 18132
Showing the first eight; more decompositions exist.
