Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27564, here are decompositions:
- 13 + 27551 = 27564
- 23 + 27541 = 27564
- 37 + 27527 = 27564
- 83 + 27481 = 27564
- 107 + 27457 = 27564
- 127 + 27437 = 27564
- 137 + 27427 = 27564
- 157 + 27407 = 27564
Showing the first eight; more decompositions exist.
