Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72016, here are decompositions:

17 + 71999 = 72016
23 + 71993 = 72016
29 + 71987 = 72016
53 + 71963 = 72016
83 + 71933 = 72016
107 + 71909 = 72016
137 + 71879 = 72016
149 + 71867 = 72016

Showing the first eight; more decompositions exist.
