Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18634, here are decompositions:
- 17 + 18617 = 18634
- 41 + 18593 = 18634
- 47 + 18587 = 18634
- 113 + 18521 = 18634
- 131 + 18503 = 18634
- 173 + 18461 = 18634
- 191 + 18443 = 18634
- 233 + 18401 = 18634
Showing the first eight; more decompositions exist.
