Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28036, here are decompositions:
- 5 + 28031 = 28036
- 17 + 28019 = 28036
- 53 + 27983 = 28036
- 83 + 27953 = 28036
- 89 + 27947 = 28036
- 227 + 27809 = 28036
- 233 + 27803 = 28036
- 257 + 27779 = 28036
Showing the first eight; more decompositions exist.
