Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182272, here are decompositions:

11 + 182261 = 182272
29 + 182243 = 182272
71 + 182201 = 182272
113 + 182159 = 182272
131 + 182141 = 182272
149 + 182123 = 182272
173 + 182099 = 182272
263 + 182009 = 182272

Showing the first eight; more decompositions exist.
