Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18694, here are decompositions:
- 3 + 18691 = 18694
- 23 + 18671 = 18694
- 101 + 18593 = 18694
- 107 + 18587 = 18694
- 173 + 18521 = 18694
- 191 + 18503 = 18694
- 233 + 18461 = 18694
- 251 + 18443 = 18694
Showing the first eight; more decompositions exist.
