Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28256, here are decompositions:
- 37 + 28219 = 28256
- 73 + 28183 = 28256
- 157 + 28099 = 28256
- 199 + 28057 = 28256
- 229 + 28027 = 28256
- 313 + 27943 = 28256
- 337 + 27919 = 28256
- 373 + 27883 = 28256
Showing the first eight; more decompositions exist.
