Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18254, here are decompositions:
- 3 + 18251 = 18254
- 31 + 18223 = 18254
- 37 + 18217 = 18254
- 43 + 18211 = 18254
- 73 + 18181 = 18254
- 127 + 18127 = 18254
- 157 + 18097 = 18254
- 193 + 18061 = 18254
Showing the first eight; more decompositions exist.
