Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28328, here are decompositions:
- 19 + 28309 = 28328
- 31 + 28297 = 28328
- 109 + 28219 = 28328
- 127 + 28201 = 28328
- 229 + 28099 = 28328
- 241 + 28087 = 28328
- 271 + 28057 = 28328
- 277 + 28051 = 28328
Showing the first eight; more decompositions exist.
