Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26666, here are decompositions:
- 19 + 26647 = 26666
- 109 + 26557 = 26666
- 127 + 26539 = 26666
- 229 + 26437 = 26666
- 349 + 26317 = 26666
- 373 + 26293 = 26666
- 439 + 26227 = 26666
- 457 + 26209 = 26666
Showing the first eight; more decompositions exist.
