Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18044, here are decompositions:
- 3 + 18041 = 18044
- 31 + 18013 = 18044
- 67 + 17977 = 18044
- 73 + 17971 = 18044
- 163 + 17881 = 18044
- 181 + 17863 = 18044
- 193 + 17851 = 18044
- 283 + 17761 = 18044
Showing the first eight; more decompositions exist.
