Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42016, here are decompositions:
- 3 + 42013 = 42016
- 17 + 41999 = 42016
- 47 + 41969 = 42016
- 59 + 41957 = 42016
- 89 + 41927 = 42016
- 113 + 41903 = 42016
- 137 + 41879 = 42016
- 167 + 41849 = 42016
Showing the first eight; more decompositions exist.
