Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18706, here are decompositions:
- 5 + 18701 = 18706
- 89 + 18617 = 18706
- 113 + 18593 = 18706
- 167 + 18539 = 18706
- 263 + 18443 = 18706
- 293 + 18413 = 18706
- 353 + 18353 = 18706
- 419 + 18287 = 18706
Showing the first eight; more decompositions exist.
