Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27772, here are decompositions:
- 5 + 27767 = 27772
- 23 + 27749 = 27772
- 29 + 27743 = 27772
- 71 + 27701 = 27772
- 83 + 27689 = 27772
- 191 + 27581 = 27772
- 233 + 27539 = 27772
- 263 + 27509 = 27772
Showing the first eight; more decompositions exist.
