Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17788, here are decompositions:
- 5 + 17783 = 17788
- 41 + 17747 = 17788
- 59 + 17729 = 17788
- 107 + 17681 = 17788
- 131 + 17657 = 17788
- 179 + 17609 = 17788
- 191 + 17597 = 17788
- 269 + 17519 = 17788
Showing the first eight; more decompositions exist.
