Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27782, here are decompositions:
- 3 + 27779 = 27782
- 19 + 27763 = 27782
- 31 + 27751 = 27782
- 43 + 27739 = 27782
- 109 + 27673 = 27782
- 151 + 27631 = 27782
- 199 + 27583 = 27782
- 241 + 27541 = 27782
Showing the first eight; more decompositions exist.
