Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27724, here are decompositions:
- 23 + 27701 = 27724
- 71 + 27653 = 27724
- 107 + 27617 = 27724
- 113 + 27611 = 27724
- 173 + 27551 = 27724
- 197 + 27527 = 27724
- 293 + 27431 = 27724
- 317 + 27407 = 27724
Showing the first eight; more decompositions exist.
