Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9838, here are decompositions:
- 5 + 9833 = 9838
- 47 + 9791 = 9838
- 71 + 9767 = 9838
- 89 + 9749 = 9838
- 149 + 9689 = 9838
- 251 + 9587 = 9838
- 317 + 9521 = 9838
- 347 + 9491 = 9838
Showing the first eight; more decompositions exist.
