Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18700, here are decompositions:
- 29 + 18671 = 18700
- 83 + 18617 = 18700
- 107 + 18593 = 18700
- 113 + 18587 = 18700
- 179 + 18521 = 18700
- 197 + 18503 = 18700
- 239 + 18461 = 18700
- 257 + 18443 = 18700
Showing the first eight; more decompositions exist.
