Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13788, here are decompositions:
- 7 + 13781 = 13788
- 29 + 13759 = 13788
- 31 + 13757 = 13788
- 37 + 13751 = 13788
- 59 + 13729 = 13788
- 67 + 13721 = 13788
- 79 + 13709 = 13788
- 97 + 13691 = 13788
Showing the first eight; more decompositions exist.
