Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182872, here are decompositions:

5 + 182867 = 182872
59 + 182813 = 182872
83 + 182789 = 182872
191 + 182681 = 182872
233 + 182639 = 182872
269 + 182603 = 182872
293 + 182579 = 182872
311 + 182561 = 182872

Showing the first eight; more decompositions exist.
