Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18794, here are decompositions:
- 7 + 18787 = 18794
- 37 + 18757 = 18794
- 103 + 18691 = 18794
- 157 + 18637 = 18794
- 211 + 18583 = 18794
- 241 + 18553 = 18794
- 271 + 18523 = 18794
- 277 + 18517 = 18794
Showing the first eight; more decompositions exist.
