Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72306, here are decompositions:

19 + 72287 = 72306
29 + 72277 = 72306
37 + 72269 = 72306
53 + 72253 = 72306
79 + 72227 = 72306
83 + 72223 = 72306
137 + 72169 = 72306
139 + 72167 = 72306

Showing the first eight; more decompositions exist.
