Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27538, here are decompositions:
- 11 + 27527 = 27538
- 29 + 27509 = 27538
- 59 + 27479 = 27538
- 89 + 27449 = 27538
- 101 + 27437 = 27538
- 107 + 27431 = 27538
- 131 + 27407 = 27538
- 239 + 27299 = 27538
Showing the first eight; more decompositions exist.
