Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18676, here are decompositions:
- 5 + 18671 = 18676
- 59 + 18617 = 18676
- 83 + 18593 = 18676
- 89 + 18587 = 18676
- 137 + 18539 = 18676
- 173 + 18503 = 18676
- 233 + 18443 = 18676
- 263 + 18413 = 18676
Showing the first eight; more decompositions exist.
