Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22016, here are decompositions:

3 + 22013 = 22016
13 + 22003 = 22016
19 + 21997 = 22016
73 + 21943 = 22016
79 + 21937 = 22016
157 + 21859 = 22016
199 + 21817 = 22016
229 + 21787 = 22016

Showing the first eight; more decompositions exist.
