Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18068, here are decompositions:
- 7 + 18061 = 18068
- 19 + 18049 = 18068
- 79 + 17989 = 18068
- 97 + 17971 = 18068
- 109 + 17959 = 18068
- 139 + 17929 = 18068
- 157 + 17911 = 18068
- 229 + 17839 = 18068
Showing the first eight; more decompositions exist.
