Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18766, here are decompositions:
- 17 + 18749 = 18766
- 23 + 18743 = 18766
- 47 + 18719 = 18766
- 53 + 18713 = 18766
- 149 + 18617 = 18766
- 173 + 18593 = 18766
- 179 + 18587 = 18766
- 227 + 18539 = 18766
Showing the first eight; more decompositions exist.
