Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18084, here are decompositions:
- 7 + 18077 = 18084
- 23 + 18061 = 18084
- 37 + 18047 = 18084
- 41 + 18043 = 18084
- 43 + 18041 = 18084
- 71 + 18013 = 18084
- 97 + 17987 = 18084
- 103 + 17981 = 18084
Showing the first eight; more decompositions exist.
