Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18066, here are decompositions:
- 5 + 18061 = 18066
- 7 + 18059 = 18066
- 17 + 18049 = 18066
- 19 + 18047 = 18066
- 23 + 18043 = 18066
- 53 + 18013 = 18066
- 79 + 17987 = 18066
- 89 + 17977 = 18066
Showing the first eight; more decompositions exist.
