Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42256, here are decompositions:
- 17 + 42239 = 42256
- 29 + 42227 = 42256
- 47 + 42209 = 42256
- 59 + 42197 = 42256
- 167 + 42089 = 42256
- 173 + 42083 = 42256
- 233 + 42023 = 42256
- 239 + 42017 = 42256
Showing the first eight; more decompositions exist.
