Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27900, here are decompositions:
- 7 + 27893 = 27900
- 17 + 27883 = 27900
- 53 + 27847 = 27900
- 73 + 27827 = 27900
- 83 + 27817 = 27900
- 97 + 27803 = 27900
- 101 + 27799 = 27900
- 107 + 27793 = 27900
Showing the first eight; more decompositions exist.
