Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18994, here are decompositions:
- 47 + 18947 = 18994
- 83 + 18911 = 18994
- 191 + 18803 = 18994
- 197 + 18797 = 18994
- 251 + 18743 = 18994
- 263 + 18731 = 18994
- 281 + 18713 = 18994
- 293 + 18701 = 18994
Showing the first eight; more decompositions exist.
