Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42208, here are decompositions:
- 11 + 42197 = 42208
- 29 + 42179 = 42208
- 107 + 42101 = 42208
- 137 + 42071 = 42208
- 191 + 42017 = 42208
- 227 + 41981 = 42208
- 239 + 41969 = 42208
- 251 + 41957 = 42208
Showing the first eight; more decompositions exist.
