Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72406, here are decompositions:

23 + 72383 = 72406
53 + 72353 = 72406
137 + 72269 = 72406
179 + 72227 = 72406
233 + 72173 = 72406
239 + 72167 = 72406
317 + 72089 = 72406
353 + 72053 = 72406

Showing the first eight; more decompositions exist.
