Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42166, here are decompositions:
- 83 + 42083 = 42166
- 149 + 42017 = 42166
- 167 + 41999 = 42166
- 197 + 41969 = 42166
- 239 + 41927 = 42166
- 263 + 41903 = 42166
- 269 + 41897 = 42166
- 317 + 41849 = 42166
Showing the first eight; more decompositions exist.
