Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18074, here are decompositions:
- 13 + 18061 = 18074
- 31 + 18043 = 18074
- 61 + 18013 = 18074
- 97 + 17977 = 18074
- 103 + 17971 = 18074
- 151 + 17923 = 18074
- 163 + 17911 = 18074
- 193 + 17881 = 18074
Showing the first eight; more decompositions exist.
