Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27730, here are decompositions:
- 29 + 27701 = 27730
- 41 + 27689 = 27730
- 83 + 27647 = 27730
- 113 + 27617 = 27730
- 149 + 27581 = 27730
- 179 + 27551 = 27730
- 191 + 27539 = 27730
- 251 + 27479 = 27730
Showing the first eight; more decompositions exist.
