Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42118, here are decompositions:
- 17 + 42101 = 42118
- 29 + 42089 = 42118
- 47 + 42071 = 42118
- 101 + 42017 = 42118
- 137 + 41981 = 42118
- 149 + 41969 = 42118
- 191 + 41927 = 42118
- 239 + 41879 = 42118
Showing the first eight; more decompositions exist.
