Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27866, here are decompositions:
- 19 + 27847 = 27866
- 43 + 27823 = 27866
- 67 + 27799 = 27866
- 73 + 27793 = 27866
- 103 + 27763 = 27866
- 127 + 27739 = 27866
- 193 + 27673 = 27866
- 283 + 27583 = 27866
Showing the first eight; more decompositions exist.
