Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18016, here are decompositions:

3 + 18013 = 18016
29 + 17987 = 18016
59 + 17957 = 18016
107 + 17909 = 18016
113 + 17903 = 18016
179 + 17837 = 18016
227 + 17789 = 18016
233 + 17783 = 18016

Showing the first eight; more decompositions exist.
