Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18032, here are decompositions:

19 + 18013 = 18032
43 + 17989 = 18032
61 + 17971 = 18032
73 + 17959 = 18032
103 + 17929 = 18032
109 + 17923 = 18032
151 + 17881 = 18032
181 + 17851 = 18032

Showing the first eight; more decompositions exist.
