Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182018, here are decompositions:

7 + 182011 = 182018
37 + 181981 = 182018
61 + 181957 = 182018
127 + 181891 = 182018
181 + 181837 = 182018
229 + 181789 = 182018
241 + 181777 = 182018
307 + 181711 = 182018

Showing the first eight; more decompositions exist.
