Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13678, here are decompositions:
- 29 + 13649 = 13678
- 59 + 13619 = 13678
- 101 + 13577 = 13678
- 179 + 13499 = 13678
- 191 + 13487 = 13678
- 227 + 13451 = 13678
- 257 + 13421 = 13678
- 281 + 13397 = 13678
Showing the first eight; more decompositions exist.
