Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28066, here are decompositions:
- 47 + 28019 = 28066
- 83 + 27983 = 28066
- 113 + 27953 = 28066
- 149 + 27917 = 28066
- 173 + 27893 = 28066
- 239 + 27827 = 28066
- 257 + 27809 = 28066
- 263 + 27803 = 28066
Showing the first eight; more decompositions exist.
