Goldbach decomposition

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.
