Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27540, here are decompositions:
- 11 + 27529 = 27540
- 13 + 27527 = 27540
- 31 + 27509 = 27540
- 53 + 27487 = 27540
- 59 + 27481 = 27540
- 61 + 27479 = 27540
- 83 + 27457 = 27540
- 103 + 27437 = 27540
Showing the first eight; more decompositions exist.
