Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28364, here are decompositions:
- 13 + 28351 = 28364
- 67 + 28297 = 28364
- 163 + 28201 = 28364
- 181 + 28183 = 28364
- 241 + 28123 = 28364
- 277 + 28087 = 28364
- 283 + 28081 = 28364
- 307 + 28057 = 28364
Showing the first eight; more decompositions exist.
