Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18754, here are decompositions:
- 5 + 18749 = 18754
- 11 + 18743 = 18754
- 23 + 18731 = 18754
- 41 + 18713 = 18754
- 53 + 18701 = 18754
- 83 + 18671 = 18754
- 137 + 18617 = 18754
- 167 + 18587 = 18754
Showing the first eight; more decompositions exist.
