Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18056, here are decompositions:
- 7 + 18049 = 18056
- 13 + 18043 = 18056
- 43 + 18013 = 18056
- 67 + 17989 = 18056
- 79 + 17977 = 18056
- 97 + 17959 = 18056
- 127 + 17929 = 18056
- 193 + 17863 = 18056
Showing the first eight; more decompositions exist.
