Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182072, here are decompositions:

13 + 182059 = 182072
31 + 182041 = 182072
43 + 182029 = 182072
61 + 182011 = 182072
181 + 181891 = 182072
199 + 181873 = 182072
283 + 181789 = 182072
313 + 181759 = 182072

Showing the first eight; more decompositions exist.
