Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27748, here are decompositions:
- 5 + 27743 = 27748
- 11 + 27737 = 27748
- 47 + 27701 = 27748
- 59 + 27689 = 27748
- 101 + 27647 = 27748
- 131 + 27617 = 27748
- 137 + 27611 = 27748
- 167 + 27581 = 27748
Showing the first eight; more decompositions exist.
