Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18964, here are decompositions:
- 5 + 18959 = 18964
- 17 + 18947 = 18964
- 47 + 18917 = 18964
- 53 + 18911 = 18964
- 167 + 18797 = 18964
- 191 + 18773 = 18964
- 233 + 18731 = 18964
- 251 + 18713 = 18964
Showing the first eight; more decompositions exist.
