Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28266, here are decompositions:
- 37 + 28229 = 28266
- 47 + 28219 = 28266
- 83 + 28183 = 28266
- 103 + 28163 = 28266
- 157 + 28109 = 28266
- 167 + 28099 = 28266
- 179 + 28087 = 28266
- 197 + 28069 = 28266
Showing the first eight; more decompositions exist.
