Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26404, here are decompositions:
- 5 + 26399 = 26404
- 11 + 26393 = 26404
- 17 + 26387 = 26404
- 47 + 26357 = 26404
- 83 + 26321 = 26404
- 107 + 26297 = 26404
- 137 + 26267 = 26404
- 167 + 26237 = 26404
Showing the first eight; more decompositions exist.
